CONCENTRATED COMPLEX NATURAL LIQUID FERTILIZER AND THE PROCESS FOR PREPARING IT

This paper presents an example of success by using a natural fertilizer made fromanimal manure from farmers' households, after a minimal processing method to enrich the soil with elements of N, P and K without disturbance on natural ecosystems

ANALYTICAL CALCULATION OF WATER RETENTION CAPACITY, SPECIFIC FOR FORESTRY TERRACES SITUATED ON SLOPE DEGRADED LANDS

Terracing slopes necessitate making of "steps" along level lines, which ensures the processing of land on a certain percentage of the total area. The main constructive feature of terraced is the platform, namely width and counterslopes. Platform terraces are arranged with counterslopes, which ensures conditions for accumulation of rainwater and slows surface leaks, favoring the development of woody vegetation (trees, shrubs, fruit trees, vines) and fixes the mobilized soil by terracing action.Given the above, it raises the question of determining the water volume that canaccumulate depending on the width and terrace contraslope tilt

CONSIDERATIONS ON OBTAINING CAMELINA OIL BY COLD PRESSING

The oil obtained from oil plants have characteristics and properties that allow use for people food, animals and in some cases alternative fuel engines. Camelina is an oil plant that has properties superior to other known plants: sunflower, soybean, flax, etc., to be used as fuel, the paper presenting some considerations that make this plant as an alternative to fossil fuels
