Search the web for “sampling for plant analysis” to find guides, such as North Carolina Department of Agriculture and Consumer Services’ “Sampling for Plant Analysis” [17], to ensure the sample is from the appropriate plant tissue and growth stage. Following standard sampling guidelines will […]
www.sare.org publications conservation-tillage-systems-in-the-southeast chapter-10-soil-fertility-management animal-waste-management Animal Waste Management With no-till cropping systems, fertilizers and animal-waste nutrients are applied to the soil surface or surface residue and remain there until water infiltration carries them into the soil. The rate of microbial decomposition will be slower than with the conventional practice of incorporating animal waste, and this delays the availability of nutrients. As a result, […]

The nitrogen cycle describes the many ways nitrogen can change forms in the environment, including changes that occur on farmland (Figure 10.9). There are several common nitrogen fertilizer formulations. Most are granules or liquids containing urea, ammonium or nitrate. Manures, legume cover crops or residual plant nutrients from previous crops […]

The following standard principles apply whether using conventional or conservation tillage: Prior to sampling, check with the laboratory for information concerning sampling depth, packaging, information forms, typical laboratory turnaround time, analyses performed and fees. Contact information for state laboratories in the Southeast can […]

Sediment loss in conservation tillage as a percentage of sediment loss with no-till in Tennessee with full-season soybeans (TN 1) and double-crop soybeans (TN 2) [33], and in North Carolina with cotton (NC 1) or corn (NC 2) [9]. Tillage and residue-management practices have numerous complex effects on soil. These effects are influenced […]

Crozier, North Carolina State University Don D. Tyler, University of Tennessee Greg D. Hoyt, North Carolina State University Conservation tillage practices result in changes that affect soil fertility management on the farm. Application methods used in conservation tillage influence the distribution of lime and fertilizer in the soil profile and over the field. […]

If weather in the spring is wet or cold, and cover crop termination is delayed, herbicide application is recommended to speed up termination. Application rates less than label rate are effective in […]

The RJ transplanter, manufactured in Canada, is a typical example. It has a spring-loaded 20-inch, turbo-fluted coulter, followed by a double-disk opener and a shoe with a kicker mechanism to place the transplants in the soil. Angled steel press wheels […]

Planters designed for operation in residues are heavier than conventional planters. The additional weight allows the planter to maintain the desired seeding depth in rough soil conditions and prevents the planter from floating across the soil surface, […]
