I'm planning an experiment on young loblolly pine cuttings and I want to test different levels of fertilizer, with the operational levels as one of the treatments and then a couple of treatments with lower and higher fertilizer amounts.
Results from many countries showed that farmers who switched from surface irrigation to drip irrigation were able to reduce their water consumption by 30 to 60 percent. The resulting crop is often increased at the same time as the plants are given the optimal amount of water (and often fertilizer) when they need it
