“…Immediately after experimental plots were laid out in spring of 2009, selected soil properties to characterize site were determined on soil samples collected across the study area from the control plots at three soil depth (0-15, 15-30 and 30-60 cm) increments (Table 1). Soil was analyzed using the methods cited by [21]. The soil is deficient in available N and P, sufficient in K, and with low organic matter content and high pH.…”

Abstract:The bioenergy industry produces a wide range of byproducts varying in their chemical composition depending on type of technology employed. In particular, pyrolysis and transesterification conversion processes generate C-rich byproducts of biochar (BC) and glycerol (GL), respectively, which can be added to soil. These two byproducts vary in their carbon availability, and comparing their effects when added to agricultural soil deserves attention. This study investigated the immediate and residual effects of a single application of BC and GL to a cultivated Brown Chernozem soil from the semi-arid region of southwestern Saskatchewan, Canada. In the first season following addition of amendments, BC and GL alone had no significant impact on all measured parameters. However, when combined with 50 kg urea N¨ha´1 (BC + UR), the yields obtained were similar to those with 100 kg urea N¨ha´1 alone. The GL with urea N (GL + UR) treatment had reduced crop yield and N uptake compared to urea alone in the year of application attributed to N immobilization, but had a positive residual effect in the second year due to remineralization. Both GL and GL + UR treatments enhanced dehydrogenase activity compared to other treatments whereas BC + UR tended to decrease microbial biomass C. The crop and soil response to application of biochar was less than observed in previous studies conducted elsewhere. Direct and residual effects of glycerol addition on the crop were more evident. An application rate greater than 2.8 t¨ha´1 and 3.5 t¨ha´1 for BC and GL, respectively, may be required to induce larger responses.

“…In addition, alfalfa intercropping improved soil fertility and the development of animal husbandry while financially benefiting farmers (Sun et al, 2018). However, alfalfa is easier to manage when dehydrated, and it has a higher nutrient value than many other fertilizers made from plant matter (Qian et al, 2011). Therefore, alfalfa powder can be used as a soil amendment in mountainous/hilly areas.…”

Improving soil conditions has been an increasingly important issue in degraded hilly areas; however, the effects of plant manure on soil nutrient and plant dry matter accumulation are poorly understood. We studied the effects of alfalfa powder, decomposed chicken manure and drought in a nonplanted group (NPG) and planted walnut group (PG) soil to explore the regulatory mechanisms of plant growth and dry matter accumulation in response to soil nutrients in hilly areas. Alfalfa fertilizer increased the soil water content and organic nutrient content, and drought resulted in a high carbon to nitrogen ratio and carbon to phosphorus ratio in NPG and PG soil. In addition, fertilization changed the available nutrient content of the soil in the nonirrigated NPG and PG. Alfalfa fertilizer altered the soil micro‐element contents and leaf mineral nutrient contents, promoted the net photosynthetic rate and relative water content, and inhibited the transpiration rate, resulting in high water use efficiency in leaves. Moreover, the coupling effect of soil organic matter and soil water content affected the correlations between the organic composition and mineral nutrients and maintained leaf mineral element contents as well as the net photosynthetic rate and water use efficiency, resulting in dry matter accumulation in the leaves, shoots and roots. This study highlights that plant manure can improve soil properties and the accumulation of plant dry matter in hilly areas. Core Ideas Alfalfa powder enhanced soil fertility in mountainous/hilly areas. Alfalfa powder improved leaf nutrient contents, leaf photosynthesis and water use efficiency (WUE) in drought. Soil environmental factors were correlated with plant growth and dry matter accumulation.

“…Fertilization with organic amendments, such as compost manure/farm yard manure (FYM), alfalfa pellets/powder, distiller grain and thin stillage can have both direct (e.g., enhancing organic C in soil) and indirect (e.g., providing available nutrients after decomposition/mineralization) benefits on soil physical, chemical and biological properties, and crop yields [1][2][3][4][5][6][7][8][9]. Inorganic amendments and microbial inoculants, such as wood ash, rock phosphate, Penicillium bilaiae, MykePro, gypsum and elemental S, have been investigated for their potential as organic fertilizers in many studies, but their effectiveness to increase the availability of P or S in soil, and subsequently improve crop yield varies with nutrient source/type, severity of P, S and other nutrients deficiency in soil, soil type and climatic conditions [10][11][12][13].…”

“…Similarly, application of organic manure in a study in China increased net ammonification, net nitrification or net N mineralization rate in soil compared to control. In a growth chamber study, Qian et al [8] showed significant increase in total N in soil with application of alfalfa powder and anticipated increase in N availability to subsequent crops. In a field study in Germany, Heitkamp et al [7] found significant increase in labile N with application of FYM for four years, and the increase was strongly related to rate of FYM and also to crop yield.…”

Compared to the unamended control, mass of TOC, TON, LFOC and LFON increased with compost and alfalfa pellets in both soils. However, the increases were much more pronounced for LFOC (by 125% -133%) or LFON (by 102% -103%) than TOC (by 19% -29%) or TON (by 25% -40%). The N min also increased in these two treatments compared to the control, but the increases were much smaller for compost than alfalfa pellets. In general, residual nitrate-N increased with increasing rate of compost and alfalfa pellets in the 0 -15 and 15 -30 cm layers in both soils. Extractable P increased with compost and exchangeable K with alfalfa pellets, but only in the 0 -15 cm soil layer. Sulphate-S increased with compost, but mainly in the 30 -60 cm soil layer. Soil pH usually increased with compost and more so with wood ash, but no effect of any amendment on ammonium-N. Overall, the quantity of organic C and N, and available nutrients in soil increased with compost and/or alfalfa pellets, but the magnitude varied with amendment and/or soil type. In conclusion, our findings suggest that soil quality and fertility can be improved with these organic amendments, suggesting sustainability of production from organic crops.
