If you think about it, soil is much like the human body. Nutrients for the soil, which are necessary for plant health, come from fertilizer and other inputs. Nutrients for our bodies come from the food that we eat. Both our bodies and the soil need nutrients like potassium, carbon, oxygen, phosphorus, and iron to be healthy. These nutrients, plus many more, are required in different amounts and at different times to achieve optimal health.

Soil and Plant Health: Do Fungicides Work?

Posted by Randy Darr on Apr 9, 2017 12:00:00 PM

One of the questions I have been asked most often in recent years in regards to soil and plant health concerns the use of fungicides. The other day a client asked, “Do fungicides work?” When I answered in the affirmative, he asked, “Does using them make money?” The answer: Maybe. Utilizing fungicides to make more money for your crop is not a sure bet. There are so many variables to consider that there is no one correct answer. In this encounter with my client, he described to me his experience in 2015, when the fungicides he used merely paid for themselves. Well, that’s not why we are in this game.

Soil Sampling Defined – Discover Your Land’s Elemental Diversity

Posted by Randy Darr on Jul 26, 2016 9:03:00 AM

Throughout the history of the agricultural studies, there has been an emphasis on applying the same scientific methods that are also used in other industries. There have been many successes, but also many failures along the way. Not all scientific applications apply in agriculture due to the earth’s ever changing landscape; it’s a living system after all.

Soil science and specifically soil sampling are one of those areas of agriculture. Many times it makes you scratch your head and wonder, “what the heck happened?” Just when soil scientists feel they have a good grasp on a given action and expectation, something changes. This is what causes the expected results to differ from what was expected.
