Wolfgang Backe,Volker Bialas,Michael Egbertsanic substrates are largely governed by the activity of the soil biomass. Inhibition of microbial activity by a low or high temperature, drought, waterlogging, extremes of pH or xenobiotic substances may result in the persistence in soil of potentially decomposable and mineralizable compounds with sfatty-streak 发表于 2025-3-23 13:52:21

Wolfgang Backe,Volker Bialas,Michael Egbertser with the costs of machinery operations, became more expensive. Thus simpler alternatives to conventional plough tillage, termed minimum or conservation tillage, became attractive as offering savings in the cost of establishing crops [.]. A further incentive was the availability of herbicides forInvigorate 发表于 2025-3-24 00:47:36

erent chemical reactions take place in soil that ensures the sustainability of life. Microorganisms including bacteria, fungi, actinomyces and algae are widely distributed in soil. These natural micro flora have several advantages. They contribute to the growth and development of plants, decompositi不规则 发表于 2025-3-24 15:24:05
