Water is the most important thing for life; and day by day fresh water is going to be lesser for irrigation. And the coming time is very tough for the agriculture in term of quality irrigation water.
Dear Gaurav, there are some production environments with moisture limiting and dryland conditions, and we have to follow appropriate nutrients management (in terms of amounts/type/stage of the crops) depending upon the moisture available in the soil profile. We have to keep in mind about the achievable yield under the moisture availability situation and accordingly apply the fertilizers (amount/type/mode). Fortified inorganics/organics, foliar nutrition products, fertigation play key role under this situation. Lot of work in this regard is being done by researchers in public/corporate systems.You also have done excellent work in fortified organics and foliar nutrition, in terms of preparing fortified products, more so under variable moisture availability

Yes water is basic to life, and we need to consider a variety of things for needs to be met and ecosystems conserved. You may want to look into pelletized fertilizer that Fertilizer Companies can do. Also better training of fertilizer users on when to fertilize, season, types, amounts, avoid hot dry, and excessively rainy periods so fertilizer can get into soil and be absorbed by plants during the rapid growing season, rather than being lost in runoff or pushed too quickly through the rooting zone and into groundwater. Fertilizers are expensive so sample and do soil tests, look for plant indicators of nutrient stress. Consider water cycle, nutrient cycle for your area, and if you don't have funds for or study, keep good records in GIS on treatment dates, chemicals used, crop results, rainfall after treatment, any major events - too hot, wet, dry, etc. Eventually you will emass enough data to help make informed advice or decisions. As an expert in your country, you may not only need to publish, but go added steps to share with professionals and train fertilizer users on what best to do. Just like we have acceptably burning days to avoid wildfires, why not acceptable fertilization days for your area, when conditions are right. For pine trees and forests, I know of several low site visual indicators. You may know some or be able to find some. These indicators can also be useful to farmers, nursery owners, etc. And they may know of a few themselves that they use, like when you see plant leaves wilting, it needs water or check for insects. One size treatment does not fit all. How to best fertilize sandy soils is different than other types. So one treatment for one soil type, may be different for another.
nutrients management in rainfed and dryland regions is important and we have to develop appropriate fertilizers for these production environments
foliar nutrition seems to be important for these conditions

Many thanks to kalra sir and Mr Hansen all for such a great effort to enlighten the problem. I am thinking that if we can develop such kind of customized fertilizers with addition of different natural polymers that can absorb moisture from the atmospheric moisture/humidity and slowly release the nutrient to the plants. these kind of fertilizers are very useful for arid zone as well as rainfed agriculture, its not only supply nutrients but also can retain some part of moisture to survive the plants in very . Yes foliar nutrition is also a good alternate. Drip fertigation is another option where we can develop crop specific fertilizers and reduce the water consumption and provide nutrition at when it needed.
