The goal of this research work was to determine widespread impact kiln-produced hardwood biochar has upon temperate agricultural soil characteristics in a long-term field experiment. This dataset is supplementary to the submitted research by [1] and presents select physical and chemical characteristics of the biochar and field plots amended with hardwood biochar. Data on soil gravimetric moisture content (GMC), soil acidity and soil nitrate-N concentration at lower depth of soil under different biochar application rates is presented. Fourier Transform Infrared (FTIR) spectroscopy is provided to demonstrate the difference between fresh and aged biochar in terms of surface functional group content.

“…The results of the current study confirmed that winter rye has a great potential for capturing residual N from fall manure fields, which otherwise could have been lost to the environment. Nitrogen removed by cover crops from soil can potentially provide substantial amount of N to the succeeding crop [4,40].…”

Winter Annual Rye Seeding Date Influence on Nitrogen Recovery and Ammonia Volatilization from Late Fall Surface-Applied Manure

Dairy farmers in the northeast face challenges in the application of manure in fall and on-time planting of cool-season grasses to maximize recovery of residual N and nutrients released from fall applied manure. Ammonia emission from animal manure is a serious environmental concern and can be reduced if cover crop is integrated in the farming system. On-time planting of cover crops can reduce ammonia volatilization from fall, surface-applied manure, and prevents N loss to leaching. A two-year study was conducted in 2015 and 2016 to investigate if time of planting of winter annual rye (Secale cereale L.) along with late fall application of manure when air temperature is low can influence ammonia emission and preserve nitrogen (N) to meet the N requirement of forage rape. Three planting dates (16 September, 30 September, and 14 October) of rye cover crop with two manure application treatments including late-fall application and no manure were assessed for mitigating ammonia volatilization, and also yield and recovery of N by forage rape (Brassica napus L.). The highest rates of ammonia volatilization were detected in the first 24 hours after manure spreading regardless of the treatment. The result indicated that cover crop use significantly limited volatilization compared with no cover crop. The earliest planting date produced 3823 kg ha−1 dry matter of winter rye cover crop that was 16 and 35 percent higher than second and third dates of planting, respectively. The manured cover crop accumulated 132 kg N ha−1 when planted early. However, biomass yield of forage rape was more when planted after all cover crop treatments with manure application. Prior to forage planting, the nitrate-N content in all three soil depths (0–20, 20–40, and 40–60 cm) in the plots with manure was higher than plots with no manure. No significant differences in forage rape yield was detected among winter rye planting dates; however, forage rape planted after winter rye was higher than after no-cover crop. The results of this study suggest that when immediate incorporation of manure into soil is not feasible, establishing cover crop early and then applying manure in the late fall, is a practical management to limit nonpoint source pollution from ammonia loss.

“…Vegetables are highly nutrient-demanding crops, and high yields are usually dependent on the application of high doses of fertilizers, especially nitrogen fertilizers, raising the cost of production. There are several studies on legumes as green manure vegetable crops (Puiatti et al,2015;Zandvakili et al, 2017;Diniz et al, 2017;Adekiya et al, 2019), indicating a reduction in the need for nitrogen fertilizers (Yao et al, 2017). However, it is necessary to develop combinations of species and management forms that associate the availability of N of the legume and organic matter to the needs of the vegetables to synchronize the mineralization and the nutrient demand by the plants during the growth.…”

Successive crops of broccoli, green corn and pea after taro (Colocasia esculenta)-sunn hemp (Crotalaria juncea) consortium

Aiming to assess the residual effect of the biomass of the taro-sunn hemp consortium on the performance of the successive crops of broccoli, green corn and peas, an experiment, with 11 treatments, corresponding to the cutting of Crotalaria juncea in the taro-sunn hemp consortium (55, 70, 85, 100, 115, 130, 145, 160, 190 and 220 days after sowing - DAS) plus a control treatment (Colocasia esculenta), was performed. Soil samples were collected and chemical analysis was performed before crop establishment. Plant characteristics and productivity of broccoli, green corn and pea pods were assessed. There were no major changes in soil chemical composition. Higher values of inflorescence fresh matter and broccoli yield were observed in the treatments in which cuts of Crotalaria juncea occurred 145 DAS. The residual effect of Crotalaria juncea cuttings provided higher corn plants and a greater fresh matter of spikes with straw and productivity of commercial ears, compared to the control. There was no residual effect on the characteristics evaluated for pea. The residual effect of Crotalaria juncea cropped in a consortium with Colocasia esculenta increases broccoli yield when cut from 145 DAS and corn cropped in succession.
