“…(2019a). Measurements of soil organic C were used to calibrate initial conditions for the three organic matter pools (residue, organic, and microbial) in the nutrient component of model (Anapalli et al., 2018; Feng et al., 2015). Across soil layers, the transfer coefficients for various organic C pools, including slow residue to intermediate organic pool (.3), fast residue to fast organic pool (.7), fast organic pool to intermediate organic pool (.4), and intermediate organic pool to slow organic pool (.7), were adapted from Ma et al.…”

“…Residue cover factor type (2.5), age of surface residue (60 d), height of standing residue (15 cm), and C/N ratio (30:1) were input to the nutrient module of the model (Feng et al., 2015). The NO 3 –N and NH 4 –N concentrations from precipitation were predicted to be .7 and .2 mg L −1 at Mississippi State (Feng et al., 2015; Qi et al., 2011). Soil NO 3 –N and NH 4 –N at 1.2‐m depth were observed and used in the model run, and assumed to be the same below 1.2 m (Yang et al., 2009a).…”

The effect of cover crop (CC) on soil water balance and agricultural production is closely related to rainfall amount and distribution in rainfed cropping systems. This study used the root zone water quality model, RZWQM2, calibrated and validated with 4-yr field measurements to predict the effect of planting a winter wheat (Triticum aestivum L.) CC in a no-till rainfed corn (Zea mays L.)-soybean (Glycine max L.) rotation on soil water balance, crop yield, and grain water-use efficiency (WUE) in northeast Mississippi. Seasonal rainfall for 80 consecutive years was classified as 'wet,' 'normal,' and 'dry' years using frequency analysis, and the data sets matched chronologically to wheat, corn, and soybean growth periods were used as an input parameter in RZWQM2 simulations. During autumn and spring (early October to early April), the CC reduced deep drainage by 69 (11%), 53 (15%), and 51 mm (21%) in wet, normal, and dry years, respectively. Averaged across 40 yr, the CC decreased surface evaporation by 64 (32%) and 38 mm (24%) for corn and soybean growth periods, respectively. Wheat CC also improved soil water storage in early crop growth period during April-June in any of the three rainfall patterns. Regardless of rainfall patterns, the increase in WUE can be attributed to a decrease in evapotranspiration during cash crop period without sacrificing cash crop yield in the CC system. Introducing CC into cropping systems is beneficial to reduce annual deep drainage and evaporation while maintaining higher crop yields under different rainfall patterns.Abbreviations: CC, cover crop; ET, evapotranspiration; NCC, no cover crop; RZWQM2, root zone water quality model; WUE, water-use efficiency.

“…When the maximum PL rate was split into 30% at pre-sowing (127 kg ha -1 ) and 70% at side-dressing (297 kg ha -1 ), it may have minimized nitrate (NO 3 --N) leaching and provided better N nutrition to the plants, as opposed to the potential damage that may have been caused by the equivalent 425 kg ha -1 year -1 only at pre-sowing. With one corn crop per year for three consecutive years, an early application of PL in fall resulted in N losses of up to 37% of the total mineralized N mainly due to NO 3 --N leaching; whereas a PL application in spring resulted in N loss up to 72% of the total mineralized N mineralized via denitrification (Feng et al, 2015). The splitting of PL fertilization may have mainly prevented or minimized nutrient losses via leaching and/or laminar erosion because it rained 97.3% (318 mm) more during the first three months after corn sowing in the first period than in the last period of corn silage crop growth (Figure 1).…”

Methods and rates of poultry litter fertilization for corn silage in organic system

The creation of proper soil fertility is fundamental to the agroecological transition phase and guarantees the sustainability of organic agribusiness. In a randomized complete block design with a 3 x 2 factorial scheme with 1 additional treatment (control, without organic fertilizer), we tested three poultry litter rates (7, 14, and 21 Mg ha-1) at sowing or splitting between sowing (30%) and side-dressing (70%) for two summer corn whole-plant silage crops and for the soil chemical attributes. The splitting of the poultry litter rate during the rainy season preserves the soil K content, prevents the accumulation of soil P and increases the efficiency of the increasing yields of the organic whole-plant corn silage crop. The reapplication of pre-sowing poultry litter can lead to an accumulation of P and Ca in the soil but favors fresh matter and cob dry matter yields in the dry season. The splitting of the poultry litter rate for whole-plant corn silage can guarantee technical and environmental sustainability in rainy years, but on the other hand, the reapplication of this organic fertilizer only at pre-sowing can increase the fresh matter yield and protein quality of organic whole-plant corn silage cultivated in an Inceptisol in the dry season.
