Using field slope farmland plots, this study planted the typical crop of maize (Zea mays L.) and investigated the effects of varied chemical fertilizer (organic compound fertilizer of potassium nitrate, containing 17% each of nitrogen, phosphorus, and potassium) application levels (0.5 times the common fertilizer amount (CK, 0.75 t·hm−2 to 2.5 CK) on the soil fertility in the Yuanmou dry-hot River Valley. The results showed that the soil chemical properties, microbial properties, and enzyme activities increased with the increase of fertilizer application levels from CK to 2.0 CK. However, a declining trend showed both under 0.5 CK level and the 2.5 CK level, and higher in fertilizer application level 3 (1.5 CK) and level 4 (2.0 CK) compared to level 1 (1 CK). Soil chemical properties, microbial properties, and enzyme activities in five-degree slope cropland topsoil were higher than these in 10-degree slope cropland topsoil. Five parameters (available N, nitrifying bacteria, inorganic phosphorus bacteria, organic matter, and invertase) in five-degree slope cropland and three parameters (organic matter, ammonifying bacteria, and total P) in 10-degree slope cropland, which had the greatest weight in the principal components analysis, were selected to calculate the soil quality index (SQI). The SQI calculated by integrating all critical parameters indicated that the highest SQI values were found in fertilizer levels 1.5 CK (0.71) and 2.0 CK (0.69), followed by CK (0.64), and the lowest were found in 0.5 CK (0.62) and 2.5 CK (0.61) in five-degree slope cropland soil. The highest SQI values were found in fertilizer levels 1.5 CK (0.26) and 2.0 CK (0.29), followed by CK (0.23), and the lowest were found in 0.5 CK (0.14) and 2.5 CK (0.20) in 10-degree slope cropland soil. The final SQI values implied that the fertilization treatment 2 (CK), fertilization treatment 3 (1.5 CK) and fertilization treatment 4 (2.0 CK) could improve the soil fertility, whereas the fertilization treatment 1 (0.5 CK) and fertilization treatment 5 (2.5 CK) could decrease the soil fertility. In view of the impact of slope, the soil qualities of five-degree slope cropland of five fertilization treatments were higher than in 10-degree slope cropland. The SQI values in five-degree slope cropland soil were found higher than the SQI values in 10-degree slope cropland soil by 68.65%, 64.20%, 62.22%, 57.46%, and 67.01%, respectively. For this study, the range of fertilization tolerance was 0.75–1.50 t·hm−2 (organic compound fertilizer of potassium nitrate) in 10-degree slope plot scale and 0.75–1.13 t∙hm−2 in five-degree slope cropland soil.

Fertile agricultural land encourages people to carry out agricultural cultivation activities. But in general, it has decreased soil fertility because its managed intensively without recycling of organic matter and has an impact on decreasing soil fertility chemically such as soil organic carbon and pH then leads to low productivity. Soybean is an agricultural product that necessary to develop because the demand for soybean consumption in East Java Province has always increased. However, Indonesia has not been able to fulfil this demand. One of the technology innovations that can be applied to improve soil fertility that has low organic matter and to increasing soybean production by providing input of quality organic fertilizer in the form of compost (Tithonia and Cow Dung). So this research is important to determine the effect of application cow dung compost and tithonia on soil chemical properties, the growth of soybean crops, and the correlations between soil chemical properties and soybean growth. This study used a randomized block design with 6 treatments and 3 replications. The result showed that the application of tithonia and cow dung compost shows a significant effect on soil chemical properties, plant height, and the number of leaves, but didn’t show a significant effect on the number of branches in every observation. Based on the correlation analysis, the results show a positive correlation between soil chemical properties and soybean growth.

One of the largest strawberry-producing municipalities of Rio Grande do Sul (RS) is Turuçu, in the South of the State. The strawberry production system adopted by farmers is similar to that used in other regions in Brazil and in the world. The main difference is related to the soil management, which can change the soil chemical properties during the strawberry cycle. This study had the objective of assessing the spatial and temporal distribution of soil fertility parameters using principal component analysis (PCA). Soil sampling was based on topography, dividing the field in three thirds: upper, middle and lower. From each of these thirds, five soil samples were randomly collected in the 0-0.20 m layer, to form a composite sample for each third. Four samples were taken during the strawberry cycle and the following properties were determined: soil organic matter (OM), soil total nitrogen (N), available phosphorus (P) and potassium (K), exchangeable calcium (Ca) and magnesium (Mg), soil pH (pH), cation exchange capacity (CEC) at pH 7.0, soil base (V%) and soil aluminum saturation(m%). No spatial variation was observed for any of the studied soil fertility parameters in the strawberry fields and temporal variation was only detected for available K. Phosphorus and K contents were always high or very high from the beginning of the strawberry cycle, while pH values ranged from very low to very high. Principal component analysis allowed the clustering of all strawberry fields based on variables related to soil acidity and organic matter content.

To evaluate the effect of different fertilizer application on soil fertility under polyculture cropping system (okra, water spinach and yard long bean), a field experiment was conducted in the oil palm reclamation soil at the research farm in ICA UTM-Pagoh. There were five treatments involved which were: (T1) no fertilizer, (T2) organic fertilizer, (T3) inorganic fertilizer, (T4) organic inorganic compound fertilizer and (T5) organic + inorganic fertilizer.  The initial and final soil samples were collected to study the effect of different types of commercial fertilizer application on soil pH, electrical conductivity (EC), moisture content, soil organic carbon (SOC), total nitrogen (TN), C/N ratio, soil organic matter (SOM), bulk density and nutrients (P and K) contents in the soil surface layer (0–15 cm) of the experimented site for 14 weeks. Results showed that the soil pH was the lowest with an average of 6.05 units in T5 and was significantly higher in T1 (8.23 units). The EC value in T5 is the highest with 172.4 ds/m and lowest in T1 with an average of 25.5 ds/m. T5 showed the highest soil moisture and soil organic matter with 15.81% and 4.01% respectively. The combine application of organic and inorganic fertilizers has increased SOC and TN values compared with the T1 (control) specifically, which resulted in 3.7% and 0.33% of SOC and TN concentrations, respectively (). Bulk density showed no significant different among all the treatment with the highest value was in T4 (1.22g/cm3) and lowest in T3(1.05g/cm3). The average amounts of C/N ratio ranged from 11.11 to 13.60 between all treatments with the highest ratio in T4 (13.6). The average P and K contents were highest in T5 (1564.7 mg/kg and 1056.2 mg/kg). Thus, it showed that the application with the mixture of organic and inorganic fertilizer (T5) improved the soil condition.

The correlation of soil fertility x seed physiological potential is very important in the area of seed technology but results published with that theme are contradictory. For this reason, this study to evaluate the correlations between soil chemical properties and physiological potential of soybean seeds. On georeferenced points, both soil and seeds were sampled for analysis of soil fertility and seed physiological potential. Data were assessed by the following analyses: descriptive statistics; Pearson's linear correlation; and geostatistics. The adjusted parameters of the semivariograms were used to produce maps of spatial distribution for each variable. Organic matter content, Mn and Cu showed significant effects on seed germination. Most variables studied presented moderate to high spatial dependence. Germination and accelerated aging of seeds, and P, Ca, Mg, Mn, Cu and Zn showed a better fit to spherical semivariogram: organic matter, pH and K had a better fit to Gaussian model; and V% and Fe showed a better fit to the linear model. The values for range of spatial dependence varied from 89.9 m for P until 651.4 m for Fe. These values should be considered when new samples are collected for assessing soil fertility in this production area.

Sewage sludge from treatment plants is an important source of N and organic matter for agriculture. The objective of this study was to analyze the effect of sewage sludge and mineral fertilization on the soil chemical properties and production of five pineapple cultivars. The study was conducted in 2 x 5 factorial scheme, consisting of two different fertilizers (sewage sludge and mineral fertilizers), combined with five pineapple cultivars (‘Pérola’, ‘Vitória’, ‘Smooth Cayenne’, ‘MD-2’, and ‘IAC Fantástico’). Sewage sludge fertilization favoured soil fertility by promoting a decrease in the pH and increase in the content of soil organic matter, phosphorus, calcium, iron, and zinc, compared to soil with mineral fertilization. In pineapple plants, sewage sludge fertilization provided statistically similar yields and physic chemical fruit characteristics compared to mineral fertilization. Among cultivars, the ‘Smooth Cayenne’ presented the highest yield (125 t ha-1), followed by cultivars ‘MD-2’ and ‘IAC Fantástico’, with intermediate yields of 98 and 90 t ha-1. Cultivars ‘Pérola’ and ‘Vitória’ presented lower yields. In this context, it was observed that sewage sludge can be used in pineapple cultivars, as an alternative source of nutrients to partial replaces inorganic fertilization.
