“…The trend suggests increased soil N supply with repeated biosolids applications. This is consistent with the observations of Barbarick et al (2010), who used planar regressions to describe the effects of application rate and number of applications on grain N uptake in dryland wheat.…”

Biosolids have the potential to improve degraded soils in grain-fallow rotations. Our objectives were to determine if repeated biosolids applications in wheat ( L.)-fallow could supply adequate but not excessive N for grain production and increase soil C without creating a high risk of P loss. A replicated on-farm experiment was established in 1994 in central Washington, comparing anaerobically digested biosolids with anhydrous NH and a zero-N control. Biosolids were applied at 5, 7, and 9 Mg ha every fourth year through 2010 and incorporated 10 cm deep, while anhydrous NH plots received 56 kg ha N every second year. Grain yield and protein were determined. Soil chemical, biological, and bulk density analyses were made in 2012. Medium and high biosolids rates significantly increased grain yield (3.63 vs. 3.13 Mg ha) and protein (103 vs. 85 g kg) compared with anhydrous NH averaged across all crops. The medium biosolids rate had significantly lower bulk density (1.05 vs. 1.22 g kg) and greater total C (0-10-cm depth) (16.9 vs. 9.4 g kg), mineralizable N (156 vs. 52 mg kg), and extractable P (114 vs. 16 mg kg) than anhydrous NH. The P index site vulnerability increased from low for anhydrous NH to medium for the biosolids treatments. Soil NO-N was nearly always <10 mg N kg soil (0-30-cm depth). Medium and high biosolids rates significantly increased bacteria/fungi ratios, Gram-negative bacteria, and anaerobic bacteria markers compared with anhydrous NH. Biosolids can be an agronomically and environmentally sound management practice in wheat-fallow systems.

“…Application of optimum fertilizer doses is desirable for attaining maximum and sustainable yield of crops. Often it is felt necessary to monitor the fertility changes in a soil over years, efficiently calibrate an optimum fertilizer dose for attaining sustainable yield of a crop, and maintain maximum soil fertility under different soil and agroclimatic conditions (Barbarick, Ippolito, and McDaniel 2010;Maruthi Sankar et al 2011, 2012a. Prasad and Goswami (1992) examined the usefulness of soil fertility restoration and its management for sustainable agriculture in South Asia.…”

Field experiments were conducted during [2005][2006][2007] to test effects of nineteen treatments on turmeric rhizome yield in Alfisol at Utukur and Inceptisol at Jagtial in India. The treatments were comprised of nitrogen (N) at 0, 60, 120 and 180 kg ha −1 ; phosphorus (P) at 0, 40, 80, and 120 kg ha −1 ; and potassium (K) at 0, 50, 100, and 150 kg ha −1 . Application of 180-120-100 kg ha −1 NPK gave maximum yield of 4302 kg ha −1 in Alfisols, whereas application of 120-80-100 kg ha −1 gave 4817 kg ha −1 in Inceptisols. Regression and principal component (PC) models were calibrated through soil-plant-fertilizer variables. The regression model gave significant R 2 of 0.75 in Alfisols compared to 0.88 in Inceptisols, whereas the PC model explained variance of 66.5 percent in Alfisols and 76.3 percent in Inceptisols. Regression model through PC scores gave R 2 of 0.54 in Alfisols and 0.47 in Inceptisols. Maximum sustainability yield indexes of 58.8 and 55.5 percent by 180-120-120 kg ha −1 (Alfisol) and 67.1 and 60.6 percent Color versions of one or more of the figures in the article can be found online at www. tandfonline.com/lcss. 781 782 D. V. Ramana Reddy et al. by 120-80-100 kg ha −1 (Inceptisol) were attained based on regression and PC models respectively.

“…While high grain protein concentration is detrimental for soft wheat end uses, high protein is desirable in hard red and white winter wheats, with optimum targets of approximately 11.5 and 12.5%, respectively. Biosolids may be more appropriately suited to hard wheat production in dryland areas of the PNW, as is the case in the state of Colorado, USA [8].…”

Applications of biosolids were compared to inorganic nitrogen (N) fertilizer for two years at three locations in eastern Washington State, USA, with diverse rainfall and soft white, hard red, and hard white winter wheat (Triticum aestivumL.) cultivars. High rates of inorganic N tended to reduce yields, while grain protein responses to N rate were positive and linear for all wheat market classes. Biosolids produced 0 to 1400 kg ha−1(0 to 47%) higher grain yields than inorganic N. Wheat may have responded positively to nutrients other than N in the biosolids or to a metered N supply that limited vegetative growth and the potential for moisture stress-induced reductions in grain yield in these dryland production systems. Grain protein content with biosolids was either equal to or below grain protein with inorganic N, likely due to dilution of grain N from the higher yields achieved with biosolids. Results indicate the potential to improve dryland winter wheat yields with biosolids compared to inorganic N alone, but perhaps not to increase grain protein concentration of hard wheat when biosolids are applied immediately before planting.
