We establish the relation between optimal subsidy rates and spillovers from the sequential adoption of a new technology, we find that they evolve in the same direction over time. We show that spillovers, hence the subsidy rates, need not be monotonic. We show that when subsidy rates are...

The purpose of this research is to improve understanding of conservation tillage adoption decisions by identifying key biophysical and socio-economic factors influencing no-till adoption by grain growers across four Australian cropping regions. The study is based on interviews with 384 grain...

In this review, we present the recent developments and future prospects of improving nitrogen use efficiency (NUE) in crops using various complementary approaches. These include conventional breeding and molecular genetics, in addition to alternative farming techniques based on no-till...

The many applications of soil survey and GIS based data to agricultural development and agri-environmental research necessitates the development of econometric approaches that allows researchers to combine this fine scale data with larger scale—aggregated—dependent variable choice data while...

Soil-crop simulation models can be a valuable tool in evaluating conservation tillage practices which are viable both economically and environmentally. The objective of this study was to evaluate the ability of the DSSAT (Decision Support Systems for Agro-technology Transfer) Cropping System...

Effects of two tillage treatments and two fallow period managements under continuous maize cropping on soil temperature, soil water dynamics and maize development were evaluated over a 4-year period (2005–2008). Tillage treatments were conventional tillage with mouldboard ploughing and...

Conservation tillage and fertilization based on soil test have been promoted by the Chinese government in recent years. Their impacts on non-point source pollution were simulated using the Soil and Water Assessment Tool (SWAT) for the Liuxi River watershed, the only one local...

Rice farming in the Lower Colorado River basin of Texas, US, is a major economic engine and a major water consumer. The Lower Colorado River Authority (LCRA) and the San Antonio Water System (SAWS) sponsored a joint project from 2004 through 2009 to study the feasibility of developing and...

This paper is a micro-level investigation into the farm-level productivity and efficiency impacts of zero tillage (ZT), a prominent resource conservation technology in agriculture. Often heralded as more sustainable than its conventional tillage alternatives, ZT has a number of positive...

Organic farming has been identified as promoting soil quality even though tillage is used for weed suppression. Adopting zero tillage and other conservation tillage practices can enhance soil quality in cropping systems where synthetic agri-chemicals are relied on for crop nutrition and weed...
