Pot experiment was conducted during 1993 on ragi grown on a sandy clay loam soil to know the periodic changes in 0-15 cm soil depth on pH, organic carbon(O.C.),available N,P and K due to application of organic manure in conjunction with fertilizer. Application of organic manures alone or in combination with fertilizer increased the soil pH, organic carbon(O.C.),available N,P and K and grain yield when compared to NPK alone. The addition of FYM compared to green leaf manure and vermicompost increased soil pH significantly. The organic carbon(O.C.)content of GLM treated soil significantly superior to VC treatment but was at par with FYM treatment at all stages of plant growth. At all stages organic manures in combination with fertilizer were superior in influencing available N,P and K compared to NPK(fertilizers) alone. There was no significant difference in the grain yield due to application of organic manures individually or in combination with fertilizers compared to NPK but maximum yield was noticed on adding 50% fertilizer N as GLM + 50% N + P + K.

The profile distributions of soil organic carbon (SOC), soil organic nitrogen (SON), soil pH and soil texture were rarely investigated in the Lancangjiang River Basin. This study aims to present the vertical distributions of these soil properties and provide some insights about how they interact with each other in the two typical soil profiles. A total of 56 soil samples were collected from two soil profiles (LCJ S-1, LCJ S-2) in the Lancangjiang River Basin to analyze the profile distributions of SOC and SON and to determine the effects of soil pH and soil texture. Generally, the contents of SOC and SON decreased with increasing soil depth and SOC contents were higher than SON contents (average SOC vs. SON content: 3.87 g kg−1 vs. 1.92 g kg−1 in LCJ S-1 and 5.19 g kg−1 vs. 0.96 g kg−1 in LCJ S-2). Soil pH ranged from 4.50 to 5.74 in the two soil profiles and generally increased with increasing soil depth. According to the percentages of clay, silt, and sand, most soil samples can be categorized as silty loam. Soil pH values were negatively correlated with C/N ratios (r = −0.66, p < 0.01) and SOC contents (r = −0.52, p < 0.01). Clay contents were positively correlated with C/N ratios (r = 0.43, p < 0.05) and SOC contents (r = 0.42, p < 0.01). The results indicate that soil pH and clay are essential factors influencing the SOC spatial distributions in the two soil profiles.

Li, X. H., Han, X. Z., Li, H. B., Song, C., Yan, J. and Liang, Y. 2012. Soil chemical and biological properties affected by 21-year application of composted manure with chemical fertilizers in a Chinese Mollisol. Can. J. Soil Sci. 92: 419–428. The effects of 21-yr of application of chemical fertilizers, composted pig manure (CPM) alone, and chemical fertilizers combined with compost on soil chemical and biological properties were investigated. Soil samples (0–20cm) were collected from a long-term fertilization experiment under corn (Zea mays L.) production in 2006, prior to seeding, at the corn tasseling stage and following harvest. Fertilizer treatments were: no fertilizer (CK), nitrogen fertilizer alone (N), N + phosphorus (NP), N + P + potassium (NPK), CPM, N + CPM, N + P + CPM (NP + CPM), and N + P + K + CPM (NPK + CPM). Long-term application of N alone resulted in a reduction of soil pH by 0.38 units and reduced the available P concentration compared with CK. An increase in soil pH was seen with CPM alone and NPK + CPM. Both fertilizers sources, singly and combined, increased the total N and available N concentrations. Total P and total K concentrations were greatest with the NPK + CPM treatment. All fertilizer treatments increased the soil organic carbon (SOC), light fraction organic carbon (LFOC) and microbial biomass carbon (MBC) concentrations significantly (P < 0.05) at the tasseling stage. The NPK + CPM treatment showed the greatest increase in SOC (12%), LFOC (78%) and MBC (44%) concentrations, compared with CK. Soil enzyme activities (invertase, urease, acid and alkaline phosphatases) tended to be greater at tasseling than other sampling dates, with highest enzyme activities in the NPK + CPM treatments. These findings suggest that a long-term application of CPM combined with NPK is an efficient strategy to maintain or increase soil quality in Mollisols for sustainable agriculture.

AbstractIn recent years, producers of agricultural products have increased the use of chemical fertilizers per unit area. The goal of this research was to analyze the interaction of genotype in treatment (NPK fertilizer) on grain yield, protein content, oil content, and the starch content on 13 maize hybrids using analysis by the model of additive and multiplier effects AMMI and to evaluate genotypes, treatments, and their interactions using biplot in Hungary. Treatments include NPK0 (N: 0 kg/ha, P2O5:0 kg/ha, K2O: 0 kg/ha), NPK1 (N: 30 kg/ha, P2O5: 23 kg/ha, K2O: 27 kg/ha), NPK2 (N: 60 kg/ha, P2O5: 46 kg/ha, K2O: 54 kg/ha), NPK3 (N: 90 kg/ha, P2O5: 69 kg/ha, K2O: 81 kg/ha), NPK4 (N: 120 kg/ha, P2O5: 92 kg/ha, K2O: 108 kg/ha), NPK5 (N: 150 kg/ha, P2O5: 115 kg/ha, K2O: 135 kg/ha) in four replications based on complete randomized block design in 2019. The NPK fertilizer effects indicate that the fertilizers are different on yield genotype. AMMI analysis showed that there was a significant difference between genotypes, treatment, and the interaction effect of genotype * treatment at one percent. Besides, the maximum yield had Loupiac and NPK3 on grain yield, Loupiac and NPK2 on oil content, P0023, and NPK3 for starch content, DKC 3/ES4725 (DKC4725) and NPK3 for protein content. Also, GGE biplot analysis indicates that had maximum grain yield in Loupiac, protein content in P9978, oil content in MV Maronetta, and starch content in Sushi.

A field experiment was done for two consecutive years from 2010-11 to 2011-12 with two varieties of wheat (DBW 17 and DPW 621-50) and ten treatments of fertilizer, involving NPK, FYM and micronutrient, with an objective to maximize the crop yield. Results showed that variety DBW 17 recorded significantly higher grain yield (4.93 %), straw yield (6.31%) and HI (1.12%) as compared to DPW 621-50. There was no significant difference in yield attributes between two varieties. Application of 150 % recommended NPK fertilizers produced the maximum grain yield (6.10 t ha-1), which was 7.7 % higher over the 100% NPK fertilizers, followed by 15 t ha-1 FYM application along with 150 (5.98 t ha-1) and 125 % (5.96 t ha-1) NPK application. There had no significant effect of micronutrients (Zn, Cu, Fe & Mn) on wheat yield indicating that the soil was not deficient in those micronutrients. A significant variation was observed between two years in respect of yield and yield attributes, higher performances being recorded in 2011-12. Crop lodging was observed, with a maximum lodging of 26.4 % causing a yield reduction of up to 9.9 %. Agronomic efficiency was the maximum (13.64 kg grain kg-1 fertilizer) with the recommended rate of fertilizers and it decreased with increasing rates. Addition of FYM didn’t increase the agronomic efficiency due to inclusion of 75 kg N contribution from 15 t ha-1 of FYM.SAARC J. Agri., 14(1): 103-110 (2016)

The study presented in this paper attempts to evaluate some interpolation techniques for mapping spatial distribution of soil pH, salinity and plant cover in Hormozgan province, Iran. The relationships among environmental factors and distribution of vegetation types were also investigated. Plot sampling was applied in the study area. Landform parameters of each plot were recorded and canopy cover percentages of each species were measured while stoniness and browsing damage were estimated. Results indicated that there was a significant difference in vegetation cover for high and low slope steepness. Also, vegetation cover was greater than other cases in the mountains with calcareous lithology. In general, there were no significant relationships among vegetation cover and soil properties such as pH, EC, and texture. Other soil properties, such as soil depth and gravel percentage were significantly affected by vegetation cover. Moreover, the geostatistical results showed that kriging and cokriging methods were better than inverse distance weighting (IDW) method for prediction of the spatial distribution of soil properties. Also, the results indicated that all the concerned soil and plant parameters were better determined by means of a cokriging method. Land elevation, which was highly correlated with studied parameters, was used as an auxiliary parameter.

Aim: To investigate the effect of different organic manures on the performance of toria crop and to understand their impact on the soil properties and availability of nutrients in acidic sandy loam soil. Methodology: Three-year fixed plot study was conducted with 7 treatments viz., T1: control, T2: recommended dose of fertilizers (RDF), T3: cow dung manure @ 5 t ha-1, T4: pig dung manure @ 5 t ha-1, T5: goat dung manure @ 5 t ha-1, T6: farm yard manure (FYM) @ 5 t ha-1, and T7: vermicompost @ 5 t ha-1 replicating 3 times in a complete randomized block design. Data were collected and analysed following the standard procedures. The yield and yield attributing parameters of toria and the soil properties such as soil pH, organic carbon, microbial biomass carbon and available NPK were studied. Results: Application of different organic manures significantly affected the plant height, number of primary branches per plant, number of siliquae per branch, number of seeds siliqua and 1000-seed weight of toria crop. Addition of organic manure significantly enhanced the soil organic carbon, microbial biomass carbon and available NPK in the soil over initial, except soil pH. The cost of cultivation, gross return and net return varied from 10.50 ×103 to 23.10 ×103, 15.00 ×103 to 35.10 ×103 and 4.46 ×103 to 19.96 ×103 Rs. ha-1, respectively. The B:C ratio varied in the order of goat dung manure > cow dung manure >RDF >FYM > pig dung manure > vermicompost > control treatment. Interpretation: To achieve maximum performance with nourishment of soil quality and health, application of vermicompost was confirmed to be the best over other organic sources of nutrients primarily due to enhancement in C and N status and an increase in microbial activities in soil.

A field experiment was conducted during rabi seasons of2017-19 at Panwari village, Agra (U.P.) to assess the effect of integrated potassium management on growth, yield and uptake of nutrient in wheat (Triticum aestivum). The experiment was laidout in a randomized block design with seven treatments and three replications. The results revealed that increasing levels of K fertilizers increased the growth and yield attributes up to 90 Kg K2O ha-1 over control. But the growth and yield attributes 0f wheat were maximum with the application of 150 Kg N + 60 Kg P2O5 + 60 Kg K2O + 5 t FYM ha-1. Increasing levels of NPK fertilizers increased the yield of wheat grain and straw over control. The maximum yield of grain(5.48 t ha-1) and straw(9.60 t ha-1) were recorded with N150P60K60FYM5. The increases in grain and straw yield with this treatment were 44.2 and 29.7% over control, respectively. The crop quality in respect of content and yield of protein increased significantly with conjoint use of fertilizers and maximum values were recorded with 150 Kg N + 60 Kg P2O5 + 60 Kg K2O + 5 t FYM ha-1 treatment. Increasing levels of NPK fertilizers up to N 150 P 60 K 90 also resulted in higher uptake of NPK by the crop and highest uptake of N, P, K and S by wheat crop was recorded with N150 P60 K60 FYM5 and the lowest in control. The soil organic carbon, available N, P and K content also improved with N150 P60 K60 FYM5 over control and lowest values of these parameters were recorded in control.

Soil testing is key to soil fertility management as it serves as a fertilizer application guide to farmers, scientists and consultants. It gives information on soil nutrient status and its supplying capacity. Laboratory (LB) procedures have been the most reliable approach for soil nutrients analyses. However, it is costly and nonpoint. Thus, the use of in–situ testing kit emerges and becomes prominent. Notwithstanding, applicability of soil testing kit must be validated by laboratory test. This work aimed to examine the reliability/suitability of Soil Testing Kit® Transchem (SK) in determining selected soil nutrients in Sahel Savannah, Nigeria. Twentyfive replicate soil samples were collected from 12°47’86’’-12°20’96’’N and 4°38’37’’-4°188’02’’E, Kebbi State Nigeria and used to test soil pH, N, P, K and soil organic carbon (SOC) by SK and LB. The SK uses colour chart and comparator for rating nutrients status qualitatively into; low, medium and high and up to very high for P. The LB results were transformed to qualitative data by corresponding the values with soil rating standardinto low, medium and high. To perform statistics, weighting was done by assigning weight load to each category; low = 1, medium = 2 and high = 3. The two methods were compared using t-test, regression and descriptive analyses. Results showed non-significant difference between the two methods for soil contents of N, P and K. However, SK poorly estimated soil pH and SOC. Correlation and regression coefficients (r = 0.915 and R2 = 0.838, respectively) indicated reliability of the SK. It is concluded that SK can be reliably used for N, P, and K but not soil pH and SOC estimation for soils in Sahel savannah of Nigeria.

Introduction: Herbicide application is a vital strategy of weed control. The effects of these chemicals on the non-target soil microorganisms are very intense; have adverse impact on physicochemical parameters of the soil, which in turn affect soil fertility and plant growth. Research Gap: There are insufficient literatures on extensive monitoring of the effects of prolonged herbicides use. Existing literatures concerning analysis of effect of prolonged herbicides application on soil are not comprehensive with respect to number of soil characteristics analyzed. Aim: This study assessed the effects of Atrazine and Glyphosate on physicochemical properties and microbial population of carrot and maize farm soils, exposed to prolonged use at Songhai Delta. Place and Duration of Study: The study was conducted in Songhai Delta farms and the Department of Environmental Management and Toxicology, Federal University of Petroleum Resources, Effurun, from April to July, 2019. Methodology: These pesticides were applied according to the manufacturers’ instructions at sublethal concentrations. Their effects on soil pH, cation exchange capacity, total organic carbon, nitrates, phosphates, sulphates and microbial populations at two depths (0-15 and 15-30 cm) were assessed using standard methods. Microbial counts were carried out for total heterotrophic bacteria and fungi using the pour plate method. Results: There were variations in the different properties of the carrot and maize farm soils. Soil pH was higher in maize farm (5.91±0.10) than in carrot farm (5.88±0.06) at the depth of 15-30 cm. The pH, total organic carbon, nitrate content had no significant difference while phosphate and microbial counts were significantly different at P=.05. Conclusion: This assessment has shown that the herbicides had no influence on pH, total organic carbon, nitrate but a negative one on bacterial and fungal populations with prolonged use. A modification in physicochemical and microbiological characteristics of soil could be used to predict the fertility and health status of soils.
