| Abstract | ||
| A field experiment was carried out in sandy soil at Ismailia Agric. Res. St. To compare the effect of many soil amendments on physical properties and corn plant growth and yield. The experiment was designed in complete randomized. The investigated amendments were: 1) organic materials : 15 m3 farmyard manure, 10 m3 biofertile and 10 m3 compost per feddan. 2) inorganic materials : 1000 kg Agrosoke and 1500 kg boligrow per feddan. The studied physical and hydrophysical properties were bulk density, total porosity, hydraulic conductivity, water holding capacity, field capacity, welting point and available water. The obtained results showed that, adding 15 m3 farmyard manure gave the best results for improving soil physical and hydro-physical properties followed by biofertile and compost. Agrosok and boligrow additions had slightly effect. The improvement of physical and hydrophysical properties of the investigated sandy soil led to an increase in vegetative growth parameters and total grain yield of corn crop. | ||
