Effect of Strip Tillage on Corn Nitrogen Uptake and Residual Soil Nitrate Accumulation Compared with No-Tillage and Chisel Plow
Kucey and Schaalje, 1986; Reeves et al., 1993; Randall et al., 1997; Torbert et al., 2001). Tillage and N management systems can have a significant effect Many soil and water quality problems are associated on N use by corn (Zea mays L.) and nitrate (NO3–N) movement with conventional tillage, along with other problems that through the soil profile. Potential water quality and NO3–N loss probaff...
متن کاملComputed tomographic measurement of macroporosity in chisel-disk and no-tillage seedbeds
Methods for evaluating soil conditions as influenced by tillage are often limited to analysis of bulk samples. The application of medical computed tomography (CT) to the characterization of tillage effects on soil provides an alternative tool for measurement since it is at a more detailed scale. The objective of this study was to compare soils under conventional and notillage (NT) systems using...
متن کاملoptimization of chisel tine operation used in combined tillage machine
performance optimization of chisel tine was proposed by using a chisel plow with adjustable rake angle. effective treatments consisted of soil moisture at 0.5, 0.7 and 0.9 of plastic limit (pl), three rake angle of 30, 40 and 50 degree and speeds of to 3, 5 and 7 km h-1. the measured parameters included draft, soil disturbance area, soil upheaving area, clod mean weight diameter (mwd), specific...
متن کاملClassification and Basic Tools
A stochastic game is a multi-stage game played in discrete time where, at each stage, the stage game played depends upon a parameter called state. The value of the state evolves as a function of its current value and the actions of the players. Let I be the finite set of players and S be the set of states. For each state z in S, an I-player normal form game is specified by action sets Ai(z) for...
متن کاملSlicing from Formal Semantics: Chisel
We describe Chisel—a tool that synthesizes a program slicer directly from a given algebraic specification of a programming language operational semantics. This semantics is assumed to be a rewriting logic specification, given in Maude, while the program is a ground term of this specification. We present the tool on two types of language paradigms: high-level, imperative and low-level assembly l...
