Barnyard Manure

Barnyard manure, N fertilizer, corn stovers, and sugar beet tops were incorporated into the soil singly and in combination in an irrigated four-course rotation (sweet corn, soft spring wheat, sugar beets, and sugar beets) that completed four cycles. The application of manure at 27 t/ha every 4 yr increased the organic matter (OM), N, P, and K of the soil and increased yields of 1st-yr sugar beets by 31% in the last cycle. When 66 kg N/ha was combined with the manure, yields of 1st-yr sugar beets increased by 53%. The responses by the 2nd-yr sugar beets were smaller. Manure, and manure plus N fertilizer, increased yields of sweet corn by 11 and 28%, but wheat yields were unaffected. The benefits of manure and N fertilizer became apparent during the second cycle and increased with advancing years. The effects of the crop residue treatments were less pronounced than those of the fertility treatments and took longer to become manifest. Incorporating sugar beet tops or corn stovers into the soil increased beet and corn yields but not wheat yields. Sugar beet yields responded more to the residue treatments when grown without manure or N fertilizer than when the fertility treatments were included. Soil Ca and Mg were not affected by fertility or residue treatments. The soil amendments affected the chemical characteristics of the OM.

Crop Residue Management

Crop residue management (CRM) through conservation agriculture can improve soil productivity and crop production by preserving soil organic matter (SOM) levels. Two major benefits of surface-residue management are improved organic matter (OM) near the soil surface and boosted nutrient cycling and preservation. Larger microbial biomass and activity near the soil surface act as a pool for nutrients desirable in crop production and enhance structural stability for increased infiltration. In addition to the altered nutrient distribution within the soil profile, changes also occur in the chemical and physical properties of the soil. Improved soil C sequestration through enhanced CRM is a cost-effective option for reducing agriculture's impact on the environment. Ideally, CRM practices should be selected to optimize crop yields with negligible adverse effects on the environment. Crop residues of common agricultural crops are chief resources, not only as sources of nutrients for subsequent crops but also for amended soil, water and air quality. Maintaining and managing crop residues in agriculture can be economically beneficial to many producers and more importantly to society. Improved residue management and reduced tillage practices should be encouraged because of their beneficial role in reducing soil degradation and increasing soil productivity. Thus, farmers have a responsibility in making management decisions that will enable them to optimize crop yields and minimize environmental impacts. Multi-disciplinary and integrated efforts by a wide variety of scientists are required to design the best site-specific systems for CRM practices to enhance agricultural productivity and sustainability while minimizing environmental impacts.

An experiment on the use of wheat straw (ploughed in or composted at the rate of 53⅓ cwt./acre every second year) and NPK fertilizers in the maintenance of fertility was carried out at Rothamsted between 1933 and 1958. The effects of these treatments on the yields of the crops of the rotation used in the experiment—barley, sugar beet, potatoes—are discussed in the present paper.The treatments appear to have had no effect on crop yields through improvements to the soil caused by better structure or increased organic matter content. All the effects obtained can be attributed to changes in the supplies of available nutrients. The most important of these changes appear to have been: (1) nitrogen deficiencies due to the immobilization of soil nitrogen or nitrogen fertilizer by the straw: there is some evidence that this added to the store of slowly available nitrogen; (2) additions to potassium supplies from potassium in the straw. Factor (1) affected all three crops. Factor (2) affected potatoes, the only crop of the three to give good responses to potassium.It was found that when the straw was ploughed in directly about 0·08 ewt. N fertilizer applied to the crops for each ton of straw was sufficient to overcome losses in yield due to nitrogen deficiencies. The straw improved the yields of potatoes in the first and second years after application. Provided that allowance was made for losses of available nitrogen the yields of potatoes from ploughed-in straw were about the same as the yields obtained by adding K fertilizer to the crop, equal in amount to the potassium in the straw. When part of the fertilizers was ploughed in with the straw instead of being given directly to the crop the yields of potatoes were reduced.Compost made with NT fertilizers and straw and ploughed in with K fertilizer gave much poorer yields than were obtained by ploughing the straw in directly and applying the fertilizers to the crops. Losses of available nitrogen were severe, all the N fertilizer used in making the compost (0·15 cwt. N for each ton of straw) being either lost through drainage or immobilized by the straw. In addition, more than one half of the potassium in the straw was lost in composting.There was no evidence that any of the nitrogen immobilized in the decomposition of the straw became available in the first or second years after application. Residues from repeated applications of straw every second year over 18 years increased the yields of potatoes and sugar beet in the last 6 years of the experiment. The increases may have been due to the release of previously immobilized nitrogen.

Bolinder, M. A., Kätterer, T., Poeplau, C., Börjesson, G. and Parent, L. E. 2015. Net primary productivity and below-ground crop residue inputs for root crops: Potato (Solanum tuberosum L.) and sugar beet (Beta vulgaris L.). Can. J. Soil Sci. 95: 87–93. Root crops are significant in agro-ecosystems of temperate climates. However, the amounts of crop residues for these crop types are not well documented and they need to be accounted for in the modeling of soil organic carbon dynamics. Our objective was to review field measurements of root biomass left in the soil as crop residues at harvest for potato and sugar beet. We considered estimates for crop residue inputs as root biomass presented in the literature and some unpublished results. Our analysis showed that compared to, for example, cereals, the contribution of below-ground net primary productivity (NPP) to crop residues is at least two to three times lower for root crops. Indeed, the field measurements indicated that root biomass for topsoils only represents on average 25 to 30 g dry matter (DM) m−2 yr−1. Other estimates, albeit variable and region-specific, tended to be higher. We suggest relative plant DM allocation coefficients for agronomic yield (RP), above-ground biomass (RS) and root biomass (RR) components, expressed as a proportion of total NPP. These coefficients, representative for temperate climates (0.739:0.236:0.025 for potato and 0.626:0.357:0.017 for sugar beet), should be useful in the modeling of agro-ecosystems that include root crops.

Crop Failure

Usually crop failure due to moisture shortage in soils is very much common due to high evaporation. Sometimes famers try to combat this problem by using mulches of crop residues in the study area. However, this is also highly challenged shortage because the crop residues used as feed for animals. Therefore, using the advantage and opportunity of cover legumes as an intercrop is the solution of the problems simultaneously in addition to their contribution improving soil nutrient balance and other many fold benefits. Therefore, this study aimed for evaluating the effect of maize-legume covers intercropping on soil moisture improvement and crop yield in moisture stress areas of the study area. The entire grain yield of maize and legumes, as well as soil moisture data were collected. The result on soil moisture revealed that intercropping of maize with cowpea had better soil moisture contents during active crop development (15.98%) and after harvest (16.70%) in average as compared to the others. The current finding also showed that adopting intercropping of maize with cowpea-boosted yield by 5256.24 kg ha-1 maize and 977.45 kg ha-1 cowpea in average with higher moisture improvement as compare to the other treatments. Therefore, intercropping of maize with cowpea is important to farmers since it would provide additional crop yield with the same piece of land. However, to get considerable changes on soil and water balances, other soil physic-chemical properties and crop yields, conducting similar studies in more than two years period at permanent field plots is paramount in the future.

The article presents the results of a 3-year test of the herbicides Lontrel Grand, VDG, Piraklid, VDG and Lontrel-300, BP, used to reduce the clogging of sugar beet crops by perennial dicotyledonous root weeds and increase crop yields. In Ryazan region the conditions these malignant plants are found in almost all fields sown with sugar beets, which is particularly vulnerable because being a root crop it cannot seriously compete with weeds. With a strong contamination of the crop by perennial dicotyledonous root shoot weeds its yield may decrease by more than 50%. Tests of drugs were carried out on sugar beet cultivar Ocean sowings on the experimental field of the institute in four replications. The size of the experimental plots is 50 m2. The soil of the experimental plot is dark gray forest heavy loam, the content of humus is 3.8%, pH is 5.8 ... 6.0, the forecrop is winter wheat. The tested herbicides were introduced with the “Agrotop” backpack compression sprayer equipped with a two-meter boom, consumption rate of the working solution was 200 l / ha. Twice sprayed in the phase of cotyledon leaves and 2 - 3 pairs of real leaves of the crop, once – in the phase of 2 - 3 pairs of leaves. The development phase of perennial dicotyledonous offset weeds during the first spraying is the leaf rosette, during the second spraying the length of the sow-thistles and thistles is 10 ... 20 cm. With the level of weediness of the crops by the Cirsium arvense, Sonchus arvensis to 26 pcs / m2 the studied preparations reduced the weediness of the crops of these weeds by 85.0 - 92.0% and increased beet root crops by 2.8 - 4.4 t / ha.

Crop yields and soil analyses were compared from three 4-year, two 5-year, and two 7-year rotations. The yields of potatoes from the seven rotations were not significantly different. Barley was grown in six rotations and the yields from these were not significantly different. The yield of sugar beets from the one rotation that did not receive any manure was significantly lower than those from the other six rotations. In the rotation in which sweet corn followed sweet clover green manure the yields were significantly lower than those from the other six rotations, where the corn followed sugar beets. This presumably was a result of the phytotoxicity of the decomposing clover. Good husbandry practices such as manure and fertilizer application evidently overshadow the effect of rotations on the yields of irrigated crops. The organic matter and nitrogen of the surface 6 in. of soil were maintained in the rotations that included 3 years of alfalfa or alfalfa–brome mixture. These soil constituents were not maintained with a single year of alfalfa or with a partial green manure crop.

Agriculture’s goal to meet the needs of the increasing world population while reducing the environmental impacts of nitrogen (N) fertilizer use without compromising output has proven to be a challenge. Manure and composts have displayed the potential to increase soil fertility. However, their potential effects on nitrous oxide (N2O) and methane (CH4) emissions have not been properly understood. Using field-scaled lysimeter experiments, we conducted a one-year study to investigate N2O and CH4 emissions, their combined global warming potential (GWP: N2O + CH4) and yield-scaled GWP in a wheat-maize system. One control and six different organic fertilizer treatments receiving different types but equal amounts of N fertilization were used: synthetic N fertilizer (NPK), 30% pig manure + 70% synthetic N fertilizer (PM30), 50% pig manure + 50% synthetic N fertilizer (PM50), 70% pig manure + 30% synthetic N fertilizer (PM70), 100% pig manure (PM100), 50% cow manure-crop residue compost + 50% synthetic N fertilizer (CMRC), and 50% pig manure-crop residue compost + 50% synthetic N fertilizer (PMRC). Seasonal cumulative N2O emissions ranged from 0.39 kg N ha−1 for the PMRC treatment to 0.93 kg N ha−1 for the NPK treatment. Similar CH4 uptakes were recorded across all treatments, with values ranging from −0.68 kg C ha−1 for the PM50 treatment to −0.52 kg C ha−1 for the PM30 treatment. Compared to the NPK treatment, all the organic-amended treatments significantly decreased N2O emission by 32–58% and GWP by 30–61%. However, among the manure-amended treatments, only treatments that consisted of inorganic N with lower or equal proportions of organic manure N treatments were found to reduce N2O emissions while maintaining crop yields at high levels. Moreover, of all the organic-amended treatments, PMRC had the lowest yield-scaled GWP, owing to its ability to significantly reduce N2O emissions while maintaining high crop yields, highlighting it as the most suitable organic fertilization treatment in Sichuan basin wheat-maize systems.

Use of residual and contact herbicides was compared with cultivation for weed control on summerfallow on Regina heavy clay from 1964 to 1967, inclusive. A single spring application of desmetryne (2-isopropylamino-4-methylamino-6-methylthio-s-triazine) at 3 kg/ha gave 77 to 90% weed control without reducing wheat yields the following year. Disadvantages were incomplete weed control, and herbicide persistence in the soil with thinning of the following wheat crop in some years.Three or four applications of paraquat (1,1′-dimethyl-4,4-bipyridinium (salt)) at 1 kg/ha gave weed control equal to cultivation of summerfallow. Chemical summerfallow was equal to cultivated summerfallow in its effects on soil moisture conservation, NO3-N accumulation and crop yields. Chemical summerfallow conserved 91% of the original crop residues compared with 24% for cultivated summerfallow. This extra crop residue was sufficient to prevent serious soil erosion from wind. Paraquat is currently too expensive to compete with cultivation.
