| description | This work was carried out in an experimental area of cacan near kvi 30 of the Manaus-Itacoatiava highway.
The modifications in the chemical composition of the superficial layer of solo (up to 20 cm deep), in amamelos latosolos (85 percent of the total bed of the Central Amazon) and in biomorphic solos (approximately 1 percent of the same area) were studied, before and after the burning of the felled forest
It was observed that fertility, under natural conditions, is low in the two types studied alone. During burning, a significant amount of nutrients are lost in the form of volatile and particulate substances, and a large amount of nutrients is rapidly released and deposited on the soil. A large amount of these temporarily available nutrients are lost through leaching, since the plants' absorption capacity is insufficient to utilize them. The current availability of nutrients has been significantly reduced due to solid fixation
It is concluded, based on the results obtained, that the nutrient return caused by burning is not capable of guaranteeing tropical agriculture in the long term. pH correction and the use of good fertilizers are necessary, as is the use of herbicides, insecticides, and fungicides to reduce root competition and plant diseases. It is advisable to establish favorable conditions for protection against the impact of atmospheric agents through the use of shading, observing the requirements of each crop. |
