Can wheat be cultivated on sandy soil and at pH 5 nearby of one of those many big rivers in Angola Huambo region?
A new farmer cleared one of those many unused land, left by former farmers in Angolan wars.
But it such land appropriate for good and economic wheat yields?
Angola imports a lot of wheat, so it forsters its own wheat production.

Absorbtion of N, P, K, S, Mg is reduced at pH5. Amount of such elements as Al , heavy metals (very toxic at ph5) , B (must be available for plant fertility and resistance), and interaction between microoelements will be very important for growth of plants.
Hello
With the rapid development of technology in agriculture, everything is possible.
You must first have a detailed analysis of the regional climate for many years. Then you should analyze the soil of the desired area and with this data, refer to the engineers and agricultural experts of the area.
They guide you in the best way.
You can also raise the pH of acidic soil by adding a lime or other alkaline compound.
The amount of lime used to correct soil acidity is influenced by various factors, including soil pH, texture (amount of sand, silt and clay), structure and amount of organic matter.
You can use different types of lime according to the water and soil conditions of the area. Some limestone sources contain micronutrients such as dolomite, which is a combination of calcium carbonate and magnesium. Therefore, if the soil is deficient in magnesium, you should use dolomite lime. But do not add to soil that has a lot of magnesium. Therefore, before using lime, be sure to do a soil test to determine whether you need Calcite lime or dolomite lime. The consumption amount should be done according to the soil test results.
Ashes from burned trees are also quite open and alkaline and can add micronutrients such as calcium, potassium, phosphate and boron to the soil. Of course, wood ash does not affect soil pH as much as lime. But it can dramatically increase soil pH over time. For this reason, you must control the soil exactly when you apply wood ash.
Keep the ash away from the roots of any plants or sprouting seedlings, as it may damage them.
Wood ash also works well in sandy soil.
For best results, the calcareous material should be plowed into the soil about two to three months before planting (usually in the fall or winter) so that there is plenty of time for the soil pH to change. Lime should be placed in the root zone of the plant or 7 inches (18 cm) above the soil.
Lime has little effect on dry soils, so you should water the soil regularly.
