Agronomists.
Agronomists, biologists, botanists, ecologists, and zoologists are scientists that would be involved in testing a weed killer. Weeds can be found in water and on land and may attract invertebrates and vertebrates. Any control ideally is checked for impact on animals (biology, zoology), environments (agronomists, ecologists), plants (botany), and soils (agronomists).
Scientists who study farms, crops, and soil are known as agronomists.
Modern explorers tend to be people such as agronomists and geologists, folk who improve the economics of the land.
Agronomists conduct research on improving crop productivity, study soil fertility and quality, recommend crop management practices, and work with farmers to implement these practices. They may also evaluate new technologies and techniques to enhance agricultural sustainability and efficiency. Additionally, agronomists may provide advice on pest and weed management to help farmers maintain healthy crops.
You must first send the sample in to a laboratory to have it analyzed for the various soil qualities. Once the lab has given you the test results you can begin to make your determinations. This is a VERY complex subject, one which agronomists study for years, and therefore much too complex to be answered here. However, you can take a look at the related link below to get an idea of where to start.
An agronomist is a professional who studies and practices the science of soil management and crop production. They are responsible for analyzing soil conditions, recommending fertilizers and crop rotation techniques, and ensuring sustainable agricultural practices. Agronomists play a crucial role in increasing crop yields and promoting food security.
== == The sky is the limit The trick is to orient yourself, education and experience towards plant nutrient or crop protection products are a must. Seek employment with a fertilzer or chemical manufacturer, or large broker distributor agent, and focus on marketing the products. If you stay in the field or in the consumption arena, you will still have a good career but, the compensation will be in the high blue collar or low white collar range.
There is a wide variety of employment in Israel. Most Israelis, though, work in the service and technology industries. There are also agronomists and intellectuals. Of course, Israel also has blue collar jobs, primarily in construction and port authority. The Israeli Defense Forces also employs a large number of Israelis.
Pedologists study soil. They used to study it only in the context of soil formation and geologic history, but in recent years agronomists (scientists who study crop production) have come to recognize that there are very complex issues surrounding the interaction of soil structure, fungi, bacteria, arthopodic life, and the crop plants. So they have "joined forces," so to speak, to study how all these things work together.
Some are teachers and some are students. A rare few are paleontologists or Neurologists. Some are clerks, some are truckers and a few flip burgers. There are parish priests, prison guards, plant managers and photographers. You can find artists, artisans, architects, agronomists, bankers, bakers, busboys, barbers, chemists, cinematographers, climatologists, cooks, dentists, dogcatchers, dermatologists, divers and almost without exception any number of occupations, specialties and sub-specialties. Some require specialized credentials and education, and almost all require dedication and effort.
