The plant health pyramid is an in-depth diagram from John Kempf of the evolution of plant resistance to disease and insect pests. John clearly outlines each level, and the nutrient requirements plants need to progress from one level to the next.

John says, "The degree of plant health and immunity is based...

Developing disease suppressive soils is a fascinating area of research, with the potential to completely change how we manage plant diseases in the very near future. As we learn more about the factors which allow soils to suppress potential pathogens, we are better able to manage these influences in the field, and produce...

The commonly accepted model of plant nutrition holds that plants absorb soluble mineral ions from the soil solution through root hairs. In this model,  plants are dependent on soluble ions and adequate water supply in the soil to allow the transport of those ions to plant roots. This dependency on water and solubility has...

These tomato plants are watered 30 minutes twice a day to maintain a constant water supply as measured by an irrometer. As nutrients are absorbed by the plant roots, they follow the upward flow of water to the leaves and fruit.

 

Aside from photosynthesis, the water is used in two very different metabolic processes; respirat...

Plants which produce fruit with a high concentration of carbohydrates require a great deal of potassium for carbohydrate transport into the fruit. The fruit functions as a storage organ for sugars, and consequently, also become a storage sink for potassium. High carbohydrate fruit such as tomatoes or potatoes need a genero...

When farming the same land year after year, it is important to understand crop succession and the carryover effects that plants contribute to the soil for future crops.

 

Some of the well known benefits are nitrogen fixation and nutrient retention. If we focus only on these benefits we miss some other critical pieces. There...

Plants can tell us many things if we are willing to observe and listen. We are always looking for ways to monitor plant health and nutritional integrity in the field. When we are able to monitor nutritional integrity and correlate balanced attrition with disease and insect resistance, we have a solid basis for preventing p...

According to this report, published by Washington State University professor Chuck Benbrook, cows on a forage based diets produce milk with a much healthier lipid and essential fatty acid profile.

 

Based on personal experience with dairy nutrition on 100% grass-fed dairies, when we improve forage health and energy, the lipi...

In regenerative agriculture systems, spring begins in the fall.

 

Both annual and perennial crops have their most important Critical points of Influence (CPIs) in the spring.

 

For annual crops the most important stage is at planting and transplanting.

 

For perennial crops, the most important stage is blossoming and pollination...

An indicator that plants have reached  level three of plant health is when they begin expressing a glossy, waxy sheen on the leaf surface. This shine is a result of elevated lipid levels contributing to much thicker and stronger cell membranes. These strengthened cell walls enable plants to regulate water in the cells much...
