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.

Available in PDF, EPUB and Kindle. Book excerpt: Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

This book was released on 2012-02 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural operations affect the soil's capability for water infiltration and storage. In this doctoral thesis, agricultural impacts in terms of soil compaction and different tillage techniques on the soil hydraulic properties and the water-conducting pores were analyzed. In the first part, infiltration measurements in differently compacted subsoil treatments of an arable field in Lincoln/New Zealand were used to characterize the effects on the soil's porosity and its associated water-conducting properties. In the second part, the impact of different tillage techniques - conventional (CT), reduced (RT), and no-tillage (NT) - on the hydraulic properties of an arable field in Raasdorf/Austria and its temporal dynamics were captured by repeated measurements. In the third part, data from the tillage study was used to parameterize a soil water simulation with constant and time-variable hydraulic parameters. The results of this thesis give evidence that soil hydraulic properties are strongly altered by soil compaction and different tillage operations. The thesis also shows the importance of temporal variations of soil hydraulic properties and its incorporation in hydrological models.

Download or read book Infiltration and Runoff Parameters for Tilled and No-till Row Crops written by Andrew J. Volkmer and published by . This book was released on 2014 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infiltration and runoff are hydrologic processes that effect the amount of water available to plants, for groundwater recharge, and for stream flow. No-till planting (NT) is a management practice used to reduce soil erosion, increase water infiltration, and reduce soil water evaporation, and can have great impact on infiltration and runoff. An investigation was conducted to determine the impact of NT on infiltration and runoff when compared to tilled conditions. Runoff and precipitation data was gathered from sites at Fillmore County, NE, Phelps County, NE, the USDA-ARS North Appalachian Experimental Watersheds (NAEW) near Coshocton, OH, and the Lennoxville Research Station (LRS) in Quebec, Canada. Each site consists of at least one NT treatment, and one tilled treatment. Average curve numbers (CN) from the NRCS CN method were determined for each site. A relationship between annual series and partial duration series (PDS) was developed, and used with a standard NRCS method to determine average CN. NT CN was an average of 5 points lower than the tilled sites, indicating NT sites had less runoff than the tilled sites. It was also determined that experimental CN's were an average of 6.2 points lower than tilled CN's published in the NRCS National Engineering Handbook. A method was also developed that uses reference hydraulic conductivity (Kref) values in conjunction with land-use coefficient (CL) values to determine effective hydraulic conductivity values for different tillage types. The resultant effective hydraulic conductivity (Ke) value is used in the Green-Ampt equation to model infiltration and runoff depths. Six different methods used to determine Kref were evaluated. It was determined that using ROSETTA, WEPP, and Hydrologic Soil Group criteria for Kref with CL values resulted in the most accurate prediction of runoff depths at the Phelps County, Fillmore County, and NAEW sites. Values for CL were 3-4 times higher for NT than for tilled conditions. A comparison was made between using adjusted CN's for tilled and NT conditions, and the CL method with the Green-Ampt equation. The CN method predicted runoff depths more accurately at Phelps County, Fillmore County, and NAEW. Using ROSETTA and HSG to determine Kref with the CL method produced the most accurate runoff predictions at the two watersheds in Lancaster County, NE.
