Aberdeen MS | to water and a sponge.
Take two equal size large bowls, add the same amount of water to each. In one bowl place a large sponge (broadcast) and squeeze it a couple times letting it soak up the maximum amount of water it can. The sponge is your soil, the water is applied nutrient.
Now take a smaller sponge (banding), follow the same procedure as above. Take note on how free standing water is still in the bowl. Reduce a portion of that water, but still leave free standing water in the bowl.
The crop pulls from the free standing, leaving the sponge fully saturated. The only way water will leave the sponge is by evaporation (natural release of soil bound nutrients).
Just have to remember that a grower will never 100% deplete an applied nutrient from a field. Chemistry half life rears it's head to make that physically impossible. | |
