Short term implications of organic additives on properties of sandy and clay soils and plants grown on them

الملخص EN

Rates of 0, 10, 20 and 40 gkg^-1 of two sources of organic additives i.

e.

biogas manure and pigeon manure were applied to 3 soils ( sand, light clay and heavy clay) in 2 experiments.

The first was an incubation one in which the soils were incubated with the organic additive without growing plant and the second was in soils grown with maize (Zea mays).

The duration was 60 days.

Additives improved soil properties and plant growth.

Moisture retained at field capacity (FC and wilting point (WP and available water (AW) increased.

Soil organic matter (SOM) and cation exchange capacity (CEC) increased.

.

Maize growth yield as well as uptake of NPK increased.
