We have used the results to make grass-clover mixtures that have the greatest protein content and at the same time are well adapted to the soils and weather conditions around the biorefineries. One of the factors that has a major influence on protein extraction is drought. The experiments have shown that when grasses experience drought, they fortify their cell walls and the proteins are bound more firmly to the fibers. This is a very important knowledge, which means that the farmer must remember to turn on irrigation in the absence of rain.
However, clover and alfalfa, which are included in the grass mixtures, are not as sensitive to drought when it comes to protein extraction. Therefore, it is also important that the farmer maintains a good balance between these legumes and the grass in the field. Fortunately, many farmers are very good at this. So who knows – maybe we'll eat foods filled with climate-friendly grass proteins before we know it!
