Oils Degradation in Agricultural Machinery

KUMBÁR VOJTĚCH, DOSTÁL PETR: Oils degradation in agricultural machinery. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013, LXI, No. 5, pp. 1297–1303 Evaluating of oils condition in agricultural machinery is very important. With monitoring and evaluating we can prevent technical and economic losses. In this paper there were monitored the liquid lubricants taken from m...

Deforestation Slowdown in the Legal Amazon: Prices or Policies?

Estimating the loss of agricultural productivity in the Amazon

We propose a procedure to obtain a general estimate of the rate at which agricultural productivity declines on newly cleared land in the Brazilian Amazon. This estimated parameter has two advantages over conventional estimates. First, it is a general, average estimate that can be used in macro-scale economic analysis. Second, the estimate is derived from regional data accessible to economists r...

Agricultural settlement and soil quality in the Brazilian Amazon

This paper discusses the implications of poor or non-existent information on soil quality, at the proper scale, during the planning and implementation of settlement projects in the Brazilian Amazon. Based on data from the Machadinho settlement project, Rondônia, we show that most settlers had no knowledge about the agricultural capability of the area, did not receive technical information, coul...

Degradation of fenamiphos in agricultural production soil.

Nematicides are used to control a wide variety of nematodes on many crops; unfortunately, oftentimes the control they provide is erratic. This erratic behavior is not always predictable and has been associated with chemical, physical, and biological degradation of nematicides. Their accelerated degradation is an agricultural problem that has been observed in crop monocultures and in other crop ...
