Improving gardoud soil by using animal manures and plant residues

Abstract EN

This study is conducted at kasgail area- Northern Kordofan state.It aims at investigating the role of plant residues, such (groundnuts, sesame, cowpea and roselle and animal manures such as chicken droppings, goat, donkey and cow’s dung in improving some chemical properties (nitrogen ratio, phosphorus and potassium amounts) of gardoud soil.

The experimental design used was Replications Blocks (RCB) different with three replications.

Indore method for composting (layering sequence in buckets) was used (A, B, C, D, E, F and G).

Treatment components were mixtures in plant containers, these treatments were : Representative sample is taken for analysis for the chemical properties.

The nitrogen ratio, in case of the soil plus cowpea residues mixed with goats manures gave (1.5 %), while the soil before treatment gave (1 %).

The phosphorus amount, in case of the soil plus chicken droppings gave only 86ppm, whereas ; in case of the soil plus chicken droppings plus sesame residue gave 95.3 ppm.

In contrast, the soil before treatment showed only 31.3 ppm.

In case of potassium amount the soil plus cowpea residue gave a concentration of 7.1 ppm, whereas ; the soil plus chicken dropping gave 10.3 ppm, and the combination of groundouts residue plus the donkey’s manures gave 9.6 ppm, whereas the soil before treatment gave 5.6 ppm..

Basing on the results of this study, it is highly advised to improve the chemical properties of the Gardoud soil using plant debris under study as combined with composite.

And also its recommended to dependent on sesame residue and cow dung to improve Gardoud soil.
