EVALUATION OF THE EFFECTS OF ADDITION OF KAMAFUGITO TO SOIL IN RADISH CULTIVATION: AN INVESTIGATION FOR SUSTAINABLE AGRICULTURE

Abstract

The different types of soil that make up the agricultural part of Brazil, in most cases, present a need to replace nutrients with each harvest. The inputs and fertilizers used to correct the soil have suffered a large increase due to wars and economic policies. With the aim of proposing a practical and low-cost solution for the rural producer, an experiment was carried out, involving the use of crushed rock, commonly called rocking, on a soil, observing the effects of the elements detached from the rock to the soil, during the growth of radishes. Kamafugite rock was used in mass values between 2.44% and 28.54%, using the elements iron and phosphorus as a comparison parameter. It is noted that the availability of elements increases as the rock content increases, and that the harvested vegetables showed differences depending on the content of pulverized rock added to the soil.
