“…The fast release of K in all treatment relative to other nutrient may be attributed to its existence in the cell fluid as non structural components (Christensen 1985). Similar results were reported by Mubarak et al (2002); Attiwell (1968);Christensen (1985).…”

Background Recycling of crop residues is essential to sustain soil fertility and crop production. Therefore, it is of crucial importance to study the decomposition of crop residues particularly in the arid tropics. The decomposition and nutrient release pattern from crop residues incorporated in the soil have rarely been investigated under semiarid climatic conditions in Sudan. Decomposition and nutrient release pattern from wheat residue were investigated in a 12 week litter bag experiment under field condition. Litter bags contain 50 g wheat residue were buried in plots cultivated with guar and treated with following treatments: crop residue (CR), recommended fertilizer ? crop residue (RF ? CR), sewage sludge (SS) and non treated control (C). In each plot of each block, 12 litter bags were buried. Four bags from each treatment were retrieved at 2, 4, 6, 8, 10 and 12 weeks of decomposition. The decomposed residue was analysed for remaining dry matter (DM), nitrogen (N), phosphorus (P), potassium (K) calcium (Ca), and magnesium (Mg) contents. Mass loss and nutrients released from wheat residue followed the exponential model, W t = W 0 9 e -kt from which the specific decay rate constants (k) and t 0.5 and t 0.95 were calculated. Results The result show that the mineral fertilization combined with crop residues (RF ? CR) resulted in the maximum decomposition and nutrient release compared to the other treatments. The half-life (t 0.5 ) values of the treatments were in the following order: RF ? CR (6.70 weeks) \ SS (8.0 weeks) \ CR (9.60 weeks) \ C (11.91 weeks). The percentage remaining DM in the litter bags followed the order C (73.25 %) [ CR (66.45 %) [ SS (59.85 %) [ RF ? CR (53.85 %). A 50 % loss of residue N was found after 8.88 weeks in the C treatment and 5.04 weeks in RF ? CR treatment. Generally, nutrient loss from all treatments in the order ofConclusions Application of mineral fertilizer or sewage sludge enhances the decomposition of low-quality residue (wheat). Therefore, it is essential to apply fertilizer in degraded soil before incorporation of crop residue with high carbon to nitrogen ratio.

“…Data from the present study corroborate those previously reported in the literature (Mubarak et al, 2002;Balkcom et al, 2004Balkcom et al, , 2007Meso et al, 2007) and suggest that the current Extension recommendations for N credits of 22 to 67 kg N ha -1 following peanut (Caddel et al, 2006;Buntin et al, 2007;Mitchell and Phillips, 2010;Jones et al, 2011;Maguire and Heckendorn, 2011;Wright et al, 2011;VDCR, 2014;Crozier et al, 2016) are overestimated. In addition, not all of the N released from peanut residue would be available to subsequent crops because of N cycling mechanisms, including immobilization and leaching (Knops et al, 2002), particularly on typical peanut-producing sandy soils with low cation exchange capacity.…”

Residue management is an important aspect of cropping systems. Availability of plant residue N to succeeding crops depends on N mineralization rates. Cooperative Extension currently recommends 22 to 67 kg N ha -1 credit to subsequent crops following peanut (Arachis hypogaea L.), but these recommendations are not supported in the literature, nor do they specify if the credit is applied to a subsequent winter or spring crop. Th e objective of this study was to assess N release rates from residues of three peanut cultivars (NC V-11, GA 02-C, and ANorden) at two placements (surface and 10-cm deep) and two locations representing northern and southern extremes of U.S. commercial peanut production (North Carolina and Alabama). Litterbags containing the equivalent of 3.5 Mg ha -1 were placed in a completely randomized design at both locations with four replications and retrieved periodically up to 335 d aft er application. Results were fi t to single or double exponential decay models. Based on empirical models, the N credit to a subsequent winter wheat (Triticum aestivum L.) crop was estimated at 14 to 19 kg N ha -1 when peanut residues were buried aft er harvest, and 19 to 24 kg N ha -1 when on the soil surface. When N credits were applied to a subsequent cotton (Gossypium hirsutum L.) crop, they were reduced to 2 to 9 kg N ha -1 (buried) and 6 to 10 kg N ha -1 (surface). Current recommendations are higher than the results obtained in this study suggest and warrant re-examination.

“…However, crop residue benefits are only realized upon their decomposition and subsequent nutrient release which are influenced by their biochemical quality (Mubarak et al, 2002;Igbal, 2009). The quality of crop residues as a source of nutrients for plants depends on their nutrient concentration and amounts released on decomposition (Mwangi et al, 2013).…”

Crop residues have the potential to enhance soil fertility, but this is dependent on their biochemical quality. A study was conducted at the National Semi-Arid Resources Research Institute-Serere, Uganda to determine the chemical composition, nutrient release patterns and rates of selected crop residues. The design used was randomized complete block design with four replications. The treatments comprised of 20g of finger millet, sorghum, cowpea and groundnut crop residues. Finger millet had the highest initial C (36.28%) and N (3.46%), cowpea had the highest initial P (0.60%) and Ca (0.30%) and groundnut shells had significantly the highest initial K (1.01%). Finger millet husks with the lowest carbon/nitrogen ratio, had significantly the highest rate of dry matter disappearance and nutrient release, while groundnut shells with the highest carbon/nitrogen and carbon/phosphorus ratios had significantly the lowest nutrient release and dry matter disappearance rates. At the end of incubation, finger millet husks had significantly the lowest N (0.29%) and C (10.22%), while cowpea husks had the lowest P (0.27%), K (0.18%) and Ca (0.27%). Nutrient release and dry matter disappearance rates of crop residues occurred in the order of N > K > P > Ca and finger millet husks > cowpea husks > sorghum husks > groundnut shells, respectively. This study has demonstrated that finger millet husks released nutrients faster and this is beneficial for early planted crops, while groundnut shells released nutrients slowly which is appropriate for long term availability of plant nutrients.
