Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus has been identified as the nutrient element most limiting to the growth of algae in Lake Erie. In addition, nutrient loadings by tributaries are a major source of phosphorus to the lake; of this load, the diffuse load, and especially the agricultural diffuse load is a major component of the total P input to Lake Erie. The particulate P load carried by a stream has several sources: native soil P, P from fertilizer, manure, and waste, P from crop residues and detritus. The bulk of sediment-P, however, is native soil P except where additions of manure have been heavy over many years. In light of these issues, a study was initiated to investigate levels of available-P in agricultural soils in the Lake Erie drainage basin. This report is concerned with two major objectives: (1) To survey actual field levels of available P in a county in Ohio and compare these with published soil test summary data for the same area; and (2) to determine if similar data were available in other Lake Erie Basin states and to determine if soil test methods and recommendations varied significantly from state to state.

This book was released on 1982 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available phosphorus soil test levels in Ohio and Michigan agricultural soils have increased steadily since the 1960's. These increases are reported here, by county, for those counties in the Lake Erie Basin of these two states. An economic analysis of phosphate fertilizer use in Ohio Lake Erie Basin counties for corn, soybeans and wheat, shows that there is an overuse of phosphate on corn and insufficient P fertilization of soybeans. P fertilizer use on wheat is at the economic optimum. The dissolved and particulate phosphate load reductions which could be obtained by reducing available P in agricultural soils from their 1980 levels down to the sufficiency level for corn and soybeans were estimated for the Ohio and Michigan Lake Erie counties. Reductions were small compared to the reductions which could be achieved with conservation tillage, but could become more significant if available phosphorus level in Basin agricultural soils continue to rise. The costs and phosphorus reductions obtainable with a side range of agricultural management practices were compared. Conservation tillage offered the most cost-effective means of greatly reducing the agricultural diffuse phosphorus load to Lake Erie. (Author).

Download or read book Phosphorus in Soils and Plants written by Naser A. Anjum and published by BoD – Books on Demand. This book was released on 2024-01-31 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) stands second to nitrogen in terms of its essentiality as a plant macronutrient, as well as due to its involvement in almost all plant developmental stages, primary and secondary plant metabolisms, maintenance of membrane structures, and in the structural skeleton of major biomolecules. An optimum P-supply also helps plants combat abiotic stress impacts. Most P in soil remains unavailable for uptake by plants. P-containing fertilizers are being added to agricultural lands to sustain high yields. Only the least amount of the applied P (20%–30%) is used by most cultivated plants, and the rest remains as legacy P (P surpluses), which eventually causes eutrophication. This book, Phosphorus in Soils and Plants, reviews P in soils and plants, P dynamics in the soil–water–sediment environment, the major roles of P in the photosynthetic dark phase-biochemical pathways, major approaches for the sustainable management of P in agriculture, main mechanisms underlying the role of P in the regulation of plant–microbe interactions in the rhizosphere, literature on the role of microbial phosphate solubilization in management of soil and plant nutrients, and insights into P recovery through waste transformation. This volume is an important resource for plant biologists involved in teaching or research who wish to advance their knowledge of P in soils and plants.
Book Synopsis The Effects of Reduced Tillage on Phosphate Transport from Agricultural Land by : Terry J. Logan
Download or read book The Effects of Reduced Tillage on Phosphate Transport from Agricultural Land written by Terry J. Logan and published by . This book was released on 1981 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report examines and summarizes published and some unpublished data on the relative effects of conservation tillage (primarily no till) versus conventional tillage on surface runoff, soil loss and phosphorus loss. The data show that conservation tillage increased runoff relative to conventional tillage on soils with poor internal drainage and reduced runoff on more permeable soils. Conservation tillage greatly reduced soil loss and total particulate P (TPP) loss, but the percent reduction of TPP was only 89% of the percent reduction in soil loss. Conservation tillage increased soluble P (OP) losses in all cases. Conservation tillage was less effective in reducing plant-available (Bray P1) phosphate than in reducing TPP. P fertilization in excess of crop needs increased soluble P losses in runoff, and the effect of P fertilization on soluble P losses was greatest with no till because of P accumulation at the surface.
