Data are given on the changes induced in the physical properties of the soil in a factorial experimant in which cultural, irrigation, and nitrogen treatments are tested on citrus. Apart from increase in the non-capillary porosity of the surface layer to the depth of cultivation, there is no difference to be noted in porosity between the cultivated plots with the addition of organic matter and the uncultivated bare surface plots where no organic matter is added. Under permanent sod the total non-capillary porosity is reduced but larger pores are present, 44 per cent. being in the form insect burrows 2 mm. and more in diameter. |
