SOIL ANALYSIS

Soil Analysis

Soil analysis is crucial in establishing crops. Cultivated pasture is no exception. Soil analysis will give you the advantage of improving your chances for success. Your local fertilizer supplier will be able to perform a typical soil analysis at minimum cost.

 

Brasuda Grass Soil Fertility Requirements:

Pennisetum spp. (Carajas) has the highest soil fertility requirements, which is followed by Panicum spp.  (Mombasa, Tanzania and Aries) and Brachiaria spp. (Marandu, MG-4, MG-5).

Soil Nutrient Analysis Variables:

S = Ca + Mg + K + Na

CEC = Ca + Mg + K + Na + Al + H

CEC: Cation exchange capacity is the total capacity of a soil to hold exchangeable cations. It influences the soil’s ability to hold onto essential nutrients and provides a buffer against soil acidification. Soils with a higher clay fraction tend to have a higher CEC. Organic matter has a very high CEC.

S: the sum of basic cations.

Guide to Basic Nutrient Replacement

    • From the dry matter that is removed from the area you must replace the amounts of nutrients as above.
    • Calcium (Ca) and Magnesium (Mg) are not required as far as your soil pH is above 5.5.
    • Nitrogen must be split in 2 to 4 times during the year due to natural losses.
    • Nutrient replacement for the dry matter harvested for hay, silage or green crop-making:
