“…Poultry litter (PL), which has proven to be an excellent row crop fertilizer (Tewolde & Sistani, 2014; Tewolde et al., 2016), is composed of mostly organic matter (≈60%) and is a rich source of all mineral elements needed for healthy plant growth (Tewolde et al., 2005a, 2005b). However, the mineral elements in PL do not exist in proportions needed for plant growth.…”

Applying poultry litter (PL) to meet a crop's P need is the most recommended PL management practice but may not be the most ideal. In this study, alternative management strategies that included the rotations of crops and fertilizers were tested. Cotton (Gossypium hirsutum L.), corn (Zea mays L.), and soybean [Glycine max (L.) Merr.] were grown in rotation and fertilized with five fertility treatments, which included an unfertilized control, a standard fertilization with conventional synthetic fertilizers (Std), P‐based PL application every year for 5 yr (P5L), N‐based PL application every year for 5 yr (N5L), and N‐based PL application each of the first 2 yr and a synthetic N application at the same rate as the Std in the last 3 yr (N2L). The level of residual soil mineral elements was assessed after 5 yr of imposing these treatments. The results showed that, relative to the Std, the N5L treatment elevated extractable soil P, Cu, and Zn by >100% and soil K and Mg by ≈90%. After 5 yr, soil nutrient levels in the N2L treatment were comparable to the P5L treatment, which did not lead to any nutrient buildup. Rotating crops was not a reliable practice for purposes of managing soil nutrient buildup. The results overall show that applying PL at a relatively high rate to meet the N need of cotton for a few years and suspending the application for 2–3 yr during which only synthetic N fertilizer is applied offers an effective and sustainable PL management strategy in row crop production systems.

“…Stalk residue retention and fertilization in arid areas can increase the input of organic materials to soil. The size of the active organic C pool is increased because stalk residue retention and fertilization provide C for microbial activity (Roper et al, 2010), thus increasing microbial C content (Jiang et al, 2014) and the rate of organic matter decomposition (Tewolde and Sistani, 2014). Therefore, stalk residue retention and fertilization increased soil organic C pool activity, enhanced soil microbial activity, and promoted soil nutrient conversion.…”

Core Ideas Stalk residue retention and fertilizer increased organic carbon, total nitrogen, and microbial biomass carbon. Nitrogen‐phosphorus‐potassium plus poultry manure had the highest NO3–‐N and available nitrogen contents. Stalk residue retention plus fertilization had positive rhizospheric effect on soil organic carbon and NO3–‐N. Stalk residue retention plus fertilization had negative rhizospheric effect on total nitrogen and NH4+‐N. Stalk residue retention plus fertilization had no net rhizospheric effect on pH and microbial biomass carbon. ABSTRACT By using less chemical fertilizer to produce cotton (Gossypium hirsutum L.), farmers could reduce input costs, increase efficiency, and protect the environment. The objective of this study was to determine the effects of stalk residue management and fertilizer application on the rhizospheric and bulk soil properties. The split‐plot design included two main plot treatments (stalk residue removal and stalk residue retention) and four subplot fertilizer treatments (no fertilizer; N, P, and K fertilizer; poultry manure; and NPK plus poultry manure). Results showed that stalk residue retention increased soil pH, whereas fertilization reduced it. Stalk residue retention and fertilizer application both increased organic C, total N, and microbial biomass C. The NPK plus poultry manure treatment had the highest nitrate (NO3–‐N) and available N contents. Stalk residue retention had negative rhizospheric effect on soil pH, total N, and ammonium (NH4+‐N) but positive rhizospheric effect on soil organic C, microbial biomass C, and NO3–‐N. The NPK plus poultry manure treatment had positive rhizospheric effect on soil pH, organic C, and NO3–‐N but negative rhizospheric effect on total soil N, microbial biomass C and NH4+‐N. Overall, stalk residue retention plus fertilization had positive rhizospheric effect on soil organic C and NO3–‐N, negative rhizospheric effect on total N and NH4+‐N, and no net rhizospheric effect on soil pH and microbial biomass C. Stalk residue retention improved soil quality and increased soil organic C and available N. Stalk residue retention plus NPK fertilizer and poultry manure can significantly increase soil organic C and active C components, thus ensuring high productivity.

“…The total organic carbon (TOC) contents were determined by oxidation in dichromate solution, while total nitrogen (TN) contents were obtained by micro-Kjeldahl distillation, following the method proposed by Tedesco et al (1995). Physical fractionation of the organic matter was carried out according to Cambardella & Elliot (1992), where 20 g of soil and 80 Ml of a sodium hexametaphosphate solution (7.0 g L -1 ) were stirred during 16 hours in a horizontal stirrer, and then the suspension passed through a 53 µm sieve with the aid of water jets.…”

“…The poultry industry has grown significantly over the world and the large amounts of wastes produced by this activity have become an environmental concern since their improper disposal may contaminate soils and waters (Kominko et al, 2017). Thus, the use of these organic compounds in farming has been a prospective option because it is not just a sustainable model for utilization of wastes but it also favors optimal nutrients cycling (Komiyama, Kobayashi, & Yahagi, 2012), thus reducing the amounts of chemical fertilizers and corresponding costs (Tewolde & Sistani, 2014).…”

Application of poultry litter may lead to major changes in the structural and functional properties of soil. Understanding these alterations is crucial for assessing the effect of organic wastes on the soil quality and attributes. The purpose of this study was to assess the influence of use of poultry litter on increased organic matter, microbiological activity and physicochemical properties of soils in the Brazilian Cerrado and identify a group of expressive indicators of changes for the assessed attributes. The research was conducted in Fazenda Alvorada, a farm located in Portelândia/GO (Brazil), consisting of the following accumulated doses of turkey litter: T0 (without application); T1 (26.32 Mg ha-1); T2 (43.15 Mg ha-1); T3 (57.6 Mg ha-1). The experimental design consisted of randomized blocks and four replications. Sequential applications of poultry litter provide increases in the variables related to organic matter, mainly in particulate nitrogen and total nitrogen stocks. Applications of lower doses resulted in increases of microbial biomass carbon and microbial quotient. Concerning soil physicochemical properties, available phosphorus, the sum of bases and base saturation were the variables that exhibited the most significant changes with increased doses of poultry litter. The metabolic quotient was the most expressive indicator to represent soil alterations resulting from application of poultry litter.
