Information
Level 1 General description
Purpose:
A rainfall simulator was used to examine the influence of different management options on infiltration of rainfall and runoff.
Methods (brief)
The soil at 'Tarvellon' is described as an open downs cracking clay. The demonstration was carried out on a blade-cultivated sorghum-fallow. The soil was dry with some cracks present.
The rainfall simulator was applied to the following four plots:
A) Left as found , some sorghum straw cover was added to simulate a previous heavy sorghum crop, referred to as Blade plow cultivated/sorghum stubble cover (70%).
B) Left as found, but sorghum stubble removed, referred to as Blade plow cultivated/stubble removed. Two small cracks were present in this plot which absorbed runoff from 59% of area, (cover 5%).
C) Was 'cultivated' with 6 pits were created (4 per square meter) on the soil surface with a shovel to duplicate the effect of a pitting implement. This treatment is referred to as cultivated and Dimpled (cover 5%).
D) Was 'scarified' with a shovel and mattock to create conditions similar to those left behind a scarifier, very light stubble (1500 kg/ha) was added - referred to as Scarified/with stubble (cover 60%).
