WebWithout plentiful irrigation, growing high-water-use crops such as hay, as well as sunflowers and safflowers, may not leave sufficient moisture in the soil for the next crop in the rotation. Be flexible enough to adapt to annual climate and crop price variations, as well as to development of soil pathogens and plant parasitic nematodes. WebAs a result, C 4 plants have substantially higher water use efficiency than C 3 plants. Plants, like pineapple, that use the crassulacean acid metabolism (CAM) photosynthetic pathway achieve high water use efficiency by opening their stomates at night.
