Humberto Blanco, University of Nebraska soil specialist, reports - TopicsExpress

Humberto Blanco, University of Nebraska soil specialist, reports mixed results from a 50-year study to determine the effect of inorganic fertilizers on soils. “It’s clear that we need inorganic fertilizers to meet the increasing demands for food production, so it’s important to look at how the extensive use of inorganic fertilizers affects soil properties in the long term,” he says. “The hypothesis is that inorganic fertilization combined with conservation tillage—strip till, no-till, and others—may improve soil structural properties relative to conventional tillage systems.” (Source: AG Professional)
