In 1998, the Mineral Accounting System (MINAS) was introduced in The Netherlands. MINAS penalises farms with a levy if the farm nutrient surpluses exceed a certain threshold. The threshold is strict, meaning that most farmers need to change their environmental management and performance to avoid...
Agroforestry, now considered as a sustainable agricultural system, is being widely promoted all over the world especially in sub-Saharan Africa. This paper investigates the adoption of mixed inter-cropping an agroforestry tree species, Gliricidia sepium, and maize in Malawi. The differences...
This paper analyses the factors underlying the probability that Dutch pig farmers have plans to (a) stop, (b) to increase farm size and/or (re)build a barn, (c) to improve the quality of the production process and (d) to make manure processing facility at the own farm. A computer-based...
Crop simulation models are potentially useful tools in agricultural decision-making. In Italy, few applications have been recorded, and those implemented have been mainly restricted to the estimation of crop water requirements in irrigated basins or the estimation of potential crop yields. In...
Most research on efficiency of farm management focuses on the relationship between an array of individual management variables and technical performance. Few studies have analysed the relationship between the total complex of farm management and technical farm performance. The present study uses...
This paper develops a theoretical concept of uncertain control of an ecological–economic system in pest management. Uncertainty arises from imperfect knowledge of system inputs and inaccuracies in mathematical modeling, such as uncertainty about the population function of predators and prey,...
Crop models often require extensive input data sets to realistically simulate crop growth. Development of such input data sets can be difficult for some model users. The objective of this study was to evaluate the importance of variables in input data sets for crop modeling. Based on published...
