Once you determine your typical boron loss per year in cropping and due to rainfall, a few years of testing will tell you what a yearly application should be without further testing. It doesn't take much boron to make a healthy crop but it does require a bit and definitely not too much.
Does borax grow clover?
Just from personal experience, I noticed this property has a really difficult time growing clover. After we applied borax for the first time, the clover started growing just fine. I don't know if there's an actual causal relationship there, but it's a correlation I've seen on the farm.
Is borax safe to use in soil?
I think your kilo of borax to 1/4 acre is safe and over a 1/2 acre certainly is, especially spread out over years. Boron is an anion, and humus is what holds onto it, whereas calcium for example is a cation and clay soil particles is what holds onto them. Humus is organic matter, but not all organic matter is humus. Just one of the many benefits of sufficient organic matter in soil is the formation of humus, which will in turn hold onto more anions and have them available for plants and microbes. And on a side note, excessive potassium ties up boron.
How to get rid of boron in soil?
Deep watering will relieve heavy boron soil concentrations by leaching the nutrient away from the roots. In good soil, this leaching won’t cause boron deficiency in plants. The organic material used to enrich and fortify the earth will release the micronutrient back into the soil. On the other hand, lightly water the plants ...
What are the effects of boron on plants?
Effects and Use of Boron on Plants. Boron is a micronutrient necessary for plant growth. Without adequate boron in the soil, plants may appear healthy but will not flower or fruit. Water, organic matter and soil texture are all factors that affect boron in soil. The balance of too little or too much between plants and boron is a delicate one.
Why is boron important to plants?
Boron helps control the transport of sugars in plants. It is important to cell division and seed development. As a micronutrient, the amount of boron in soil is minute, but among micronutrients, boron deficiency in plants is the most common. Deep watering will relieve heavy boron soil concentrations by leaching the nutrient away from the roots.

per gallon of water) as a foliar spray will do the job. Be careful as you use boron on plants. Again, heavy boron soil concentrations are toxic.
What fertilizer is boron?

Brassicas, including certain vegetables (cauliflower, cabbage, broccoli, turnip, rutabaga, kale and others), canola and forage brassicas like rape and forage turnip are among the crops known to be sensitive to low soil boron levels. Sugar beets, apples, red beets, celery and sunflowers are also sensitive to boron deficiency.
Where does boron come from?
Plant-available boron exists in soil mostly as a neutral boric acid molecule. The source for this boron is mostly from decomposing organic matter in the soil. Many, if not most, Michigan agricultural soils contain adequate boron for good plant development. Coarse-textured soils, especially those low in organic material, are the most common places where boron deficiency occurs.
Why is coarse soil more prone to drought?
Coarse-textured soils are more prone to drought and, when soils are very dry, decomposition of organic material slows , sometimes causing boron deficiency. Boron is not bound to clay or organic matter particles and leaches through the soil profile readily, similar to nitrogen. In coarse-textured soils, this leaching is likely when wet conditions prevail.
What nutrients are recommended for soil testing?
Based on your soil type and intended crop, the nutrients recommended by the MSU soil test report may include boron.
Is boron a chemical?
Like nitrogen, the boron recommendation is not based on chemical analysis of your regular soil sample. Instead, it is based on many years of accumulated research results regarding crop response to boron. Special tests for soil content of nitrogen and boron are available through MSU Soil and Plant Nutrient Laboratory and other reputable labs.
What is the role of boron in plants?

Why is boron important for plants?
Importance of Boron in Plant Growth. Boron (B) is a micronutrient critical to the growth and health of all crops. It is a component of plant cell walls and reproductive structures. It is a mobile nutrient within the soil, meaning it is prone to movement within the soil. Because it is required in small amounts, it is important to deliver B as evenly ...
Why is boron deficiency so prevalent in sandy soils with low organic matter?
Boron deficiency is highly prevalent in sandy acidic soils with low organic matter, due to the potential for B leaching. Soils with high adsorption and retention capacity (e.g., soils with high pH and rich in clay minerals and iron or aluminum oxides) are also commonly impacted by B deficiency.

Why is it important to apply the correct amount of B at the right rate using the right source?
Make sure to compare your yield goals with current nutrient needs, and discuss options with an agronomist. Because there is a fine line between deficiency and toxicity, it’s important to apply the correct amount of B at the right rate using the right source.
How much B is in a plant?
