Our objective is to provide an optimistic strategy for reversing soil degradation by increasing public and private research efforts understand the role of biology, particularly microbiology, on health our world’s soils. We begin defining quality/soil (which we consider be interchangeable terms), characterizing healthy resources, relating significance agroecosystems their functions. examine how biology influences biological properties processes contribute sustainability agriculture ecosystem...
Continuous monoculture systems can reduce soil organic matter because of low inputs and disturbance from tillage practices. Integrated cotton ( Gossypium hirsutum ) cropping livestock production in West Texas may provide more sustainable alternatives to the traditional continuous system improve quality. Our study was conducted on a Pullman (Fine, mixed, thermic Torrertic Paleustolls) after 5 yr as complete randomized block design (three replications) that compared an integrated...
Soil microbial communities in Chihuahuan Desert grasslands generally experience highly variable spatiotemporal rainfall patterns. Changes precipitation regimes can affect belowground ecosystem processes such as decomposition and nutrient cycling by altering soil community structure function. The objective of this study was to determine if increased seasonal frequency magnitude over a 7-year period would generate persistent shift characteristics availability. We supplemented natural with...
Cotton ( Gossypium hirsutum L.) monoculture under conventional tillage has been the predominant cropping system in Southern High Plains region of United States since 1940s. This study evaluated other systems and land uses for their potential to increase soil quality enhance functioning compared with continuous cotton (Ct‐Ct), including a mixture grasses Conservation Reserve Program (CRP), pasture [ Bothriochloa bladhii (Retz) S.T. Blake] cotton–winter wheat Triticum aestivum L.)–corn Zea...
What is a resilient, healthy soil? A resilient soil capable of recovering from or adapting to stress, and the health living/biological component crucial for resiliency. Soil tightly coupled with concept quality (table 1), terms are frequently used interchangeably. The living biota represents small fraction (<0.05% dry weight), but it essential many functions overall quality. Some these key services production agriculture (1) nutrient provision cycling, (2) pest pathogen protection, (3)...
Soil C and N have long been recognized as important indicators of soil productivity. The current low levels cropland soils led to interest in sequestering with reduced tillage cropping systems the Conservation Reserve Program (CRP). Our objective was assess agroecosystem effects on pools Southern High Plains. agroecosystems included three cotton ( Gossypium hirsutum L.) systems, CRP land, native rangeland (NR). We sampled 0‐ 5‐, 5‐ 10‐, 10‐ 15‐, 15‐ 30‐cm depths at 12 farm sites five...
