Available in PDF, EPUB and Kindle. Book excerpt: Nowadays the environmental sustainability of the cropping systems is increasingly requested by the consumers. Conventional tillage practices, totally turning over the soil between the vineyard rows, may cause erosion due to rain as well as structure destruction of the soil in the long term. Conservation tillage is a soil management technique, poorly widespread in Sardinia, allowing cover cropping between vineyard rows. Furthermore, this technique makes the canopy development control of herbage possible by cutting it up during specific phenological phases. Conservation tillage usually involves direct benefits to farmers such as increasing soil fertility as well as reductionof tillage costs, soil erosion and carbon dioxide (CO2) emissions in the atmosphere. This long term trial, during at least five years aims to assess the conservation tillage impact on chemical-physical soil characteristics in comparison with traditional tillage by evaluating the change of organic matter, C.E.C. and availability of major plant nutrients in the soil and to estimate their probable rise. The field plots are located in a 35% slope condition vineyard, showing massive erosion problem and organic matter low content. A split/plot design with four replications was set up, with the comparison between conservation and traditional tillage apart as main plots. Moreover, the effects of two different irrigation levels were evaluated in the subplots of each main plot. At the beginning of the trial (2011) a pedological survey was made. Three soil profiles were described and sampled along the field slope and soil sampling in each plot were made both to characterize the soil and to find the zero point. The soil chemical and physical characteristics were monitored through a second soil sampling made at the end of 2013. Conservation tillage caused increasing organic matter content and C.E.C. values. As for major plant nutrients in soil, results were more uncertain. Grapevine yield and quality parameters did not show any negative effect when passing from conventional to conservation tillage techniques. The trial provided a preliminary positive evaluation of conservation tillage. However, more years are required to confirm this trend.

Book Synopsis Pesticide Use in the Lake Erie Basin and the Impact of Accelerated Conservation Tillage on Pesticide Use and Runoff Losses by : Terry J. Logan
Download or read book Pesticide Use in the Lake Erie Basin and the Impact of Accelerated Conservation Tillage on Pesticide Use and Runoff Losses written by Terry J. Logan and published by . This book was released on 1981 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major shift from conventional tillage to conservation tillage will be required to reduce soil loss and diffuse sources of phosphorus in the Lake Erie drainage basin. This shift will require some changes in the kinds and amounts of pesticides used and may change the losses of these compounds in runoff. Alachlor, atrazine and butylate account for about 77% of the herbicide used in Indiana, Michigan and Ohio, and carbofuran, fonofos and terbufos represent about 86% of the insecticide use. Most of the pesticides in use in the basin today are relatively nonpersistent and have low mammalian and fish toxicities. A major shift to conservation tillage will increase use of paraquat and glyphosate herbicides and reduce the use of soil-incorporated materials such as butylate and trifluralin. About 1% of applied pesticide is lost in runoff, much of it in the first event after the compound is applied. Pesticide losses are reduced with increased surface cover, but this effect decreases with pesticides that are water-soluble and have only moderate to low affinity for soil particles. Losses of pesticides from agricultural land in the Lake Erie basin are not expected to measurably change with a shift to conservation tillage. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book describes concepts, value judgments and background information on the expanding conservation tillage practices in the United States and provides a technical appraisal of the state of the art. Still, much remains to be learned about the agronomic, agricultural engineering and environmental parameters; and it is hoped that the inormation herein presented will stimulate further research toward a more integrated apporach to conversation tillage practices.

This book was released on 1992 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reports results of studies of conservation tillage effects on the environment in south-western Ontario. Part A summarizes a three-year study conducted to identify sediment & phosphorus transport from a poorly drained clay loam soil cropped to corn under three tillage practices: conventional, no-till, and ridge tillage. Water quality & corn yields were measured for all plots and compared; rainfall was measured and surface & subsurface runoff was quantified for each rainfall event. Water samples were taken & analyzed for sediment & orthophosphate. Part B summarizes a three-year study conducted on a similar soil to investigate the effects of the same three tillage systems on surface & subsurface transport of atrazine and metolachlor applied pre-emergence to corn. Each runoff-producing event was monitored to calculate the proportion of rainfall that left as runoff (which was collected to determine herbicide concentration).

This book was released on 1992 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part A of this report describes a study initiated to compare soil & nutrient losses from three tillage practices on a clay loam soil under intensive agriculture in Essex County, south-west Ontario. The tillage practices were: fall plough, spring disk, and one mid-season cultivation (conventional tillage); ridge tillage reformed in mid-season; and no tillage other than that associated with planting and fertilizer incorporation. Samples from surface runoff and drain discharge were analyzed for suspended sediment, nutrients, and herbicides. The crop planted was corn, and yield & moisture content were determined at harvest. Part B describes a study to provide data on herbicide losses from the three types of tillage for corn culture on a poorly drained, level plane soil. Total transport losses, seasonal distribution, and source of losses were measured for the three tillage practices for atrazine, its dealkylated analogue des-ethyl atrazine, and metolachlor.
