High N fertilizer and irrigation amounts applied to potato (Solanum tuberosum L.) on coarse-textured soils often result in nitrate (NO3) leaching and low recovery of applied fertilizer N. This 3-yr study compared the effects of two rates (140 and 280 kg N ha(-1)) of a single polyolefin-coated urea (PCU) application versus split applications of urea on 'Russet Burbank' potato yield and on NO3 le...

Abstract Tannic acid–acetic acid is proposed as novel and green chemicals for cobalt lithium recycling from spent lithium-ion batteries through a leaching process. The synergism of both acids was documented batch continuous studies. promotes dissolution by reducing insoluble Co 3+ into soluble 2+ , while acetic critical to improve the stabilize metals in pregnant leach solution. Based on studie...

Oil shale ash contains mineral ingredients of agricultural importance and could be used for treatment of soils. However, the ash contains several hazardous ingredients, i.e. toxic trace metals which could be mobile and create environmental concerns. Beneficial use of the oil shale ash in agriculture and forestry requires better knowledge of leaching characteristics of soil-ash systems. In this ...
