1. First, channels with a depth of 120 cm and a pistachio shell width of 100 cm in length
Custom drilled.
2 canal floors, dried branches of trees, wheat and barley straw, weeds and
Farm waste is dumped.
3- 200 kg / ha of urea is sprayed on the organic waste of the canal floor.
Because as we know, soil microorganisms to decompose straw and
They need to convert it to organic matter to nitrogen. Of course, because after pouring the soil on
Mass, anaerobic conditions are created and the decomposition of organic matter is very slow
It is better to use compost prepared from organic waste at the bottom of the canals
Be.
4- Animal manure should be consumed at the rate of 100 to 150 tons per hectare, which can be
Increase the percentage of organic matter. For every 10 tons of animal manure, equivalent to 600 to
1000 kg of humus is obtained every year. Then a mixture of fertilizers
Macro, including: 300 kg of phosphate fertilizer, 600 kg of potash fertilizer with up to 400
1000 kg of agricultural sulfur is consumed per hectare. Of course it is better
Consumption of these fertilizers is based on soil test, because it may be soil-based
No need for phosphorus or potassium fertilizers to accurately estimate types
Chemical fertilizers require soil at the garden site to a depth of at least 80 cm
Meters to be decomposed and fertilizers required for a period of at least 3 to 5 years
Be calculated. Finally, on the filled canal, a shallow creek is drilled and
Gravity irrigation is done by flooding, finally after land subsidence
And filling sediments with soil along the canal, complete leveling ground and
It is grounded and the holes of the seedlings are dug. Add in later years
Movable and immobile chemical fertilizers in the form of furrow fertilizers according to the depth
The roots penetrate. In gardens where the depth of root penetration is about 80
Cm, fertilizer with furrow fertilizer at a depth of 40-30 cm is correct
It does not seem. In the case of nitrogen fertilizers, it is better to use it as a road
To be.
