Sustainable Agriculture and Boron

Welcome back to the Borates Today podcast. Each week we cover a topic that is relevant to the industry and timely. We cover the latest industry news. Who are the key players in the sector? What are the latest trends, driving demand, and supply for boron. What is the science behind boron and who’s doing valuable research into new boron applications and benefits?

We look at how boron helps in advanced energy, in food security, and in providing nutrition. So don’t forget to check out boron applications and benefits on our website borates.today.

In today’s podcast, we’re going to look at sustainable agriculture. Sustainable agriculture uses micronutrients such as boron, zinc, and copper to promote soil health and support healthy plant growth. But what exactly is sustainable agriculture? And how is this achieved using proper micronutrients?

Sustainable Agriculture

Sustainable agriculture is based on the principle of using farming practices that meet society’s current food and textile needs without compromising the ability of future generations to do the same. In other words, sustainable agriculture produces food and other essential goods in a way that does not damage or deplete the natural resources upon which our existence depends.

There are a number of different approaches to sustainable agriculture. But all share a common goal, which is to create an environmentally, socially, and economically sustainable system. To achieve this, farmers employ various techniques designed to minimize the impact on the environment while maximizing yield.

These techniques can include using more efficient irrigation systems, planting cover crops to improve soil health, and carefully monitoring the nutrient content of fertilizer applications.

Stability

The benefits to adopting such practices include reduced reliance on fossil fuels and other non-renewable resources, reduced use of toxic chemicals in agricultural production, and improved ability to adapt, to changing environmental conditions like rising temperatures or changing rainfall patterns.

As climate change continues to impact food systems worldwide, sustainable agriculture will be increasingly important and ensure a stable future for society and the environment.

By making changes today towards more sustainable farming practices, there is the possibility of creating a better tomorrow for everyone on the planet.

Factors Affecting Sustainability

The most important factors that contribute to sustainability, are climate, soil, nutrients, and water resources. Out of these, water and soil conservation are the two factors that involve human activities. While growing and harvesting crops, farmers remove nutrients from the soil. Without replenishment, the land loses nutrients and becomes unusable or produces lower yields.

Sustainable agriculture is based on replenishing the soil while reducing the use or need for non-renewable resources like natural gas or mineral ores. A farm that consistently produces, but harms environmental quality somewhere else is not practicing sustainable agriculture.

An example of this is the use of fertilizer or manure, which can increase farm productivity but contaminates nearby rivers and coastal waters, a phenomenon known as eutrophication. The other extreme is also undesirable where low crop yields lead to nutrient exhaustion in the soil and rainforest destruction.

What Type of Nutrients Can Affect Sustainable Agriculture?

Well, nutrients are essential for plant growth and development and sustainable agricultural practices rely on healthy soil in order to produce the abundant crops. There are many different nutrients that plants need, including nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, and of course, boron.

Each of these nutrients is absorbed by the plant through various pathways in the soil. Nitrogen is an important nutrient for crop production because it increases yields and also helps prevent plant diseases. Most crops require a moderate amount of nitrogen to grow well, but too much or too little can be detrimental to the health of the plant.

Phosphorus is another crucial nutrient for plants as it’s necessary for maintaining profitable crop and livestock production. It also enhances the biological productivity of surface water.

As for boron, it helps regulate water retention, germination, and seed production in plants. It also plays a vital role in disease resistance and pest control making it a key component of sustainable agriculture.

Boron also helps to balance sugar and starch, enabling proper cell wall formation and seed reproduction. It directly impacts the seed and fruit structure allowing for a higher agricultural yield.

Boron requirements and tolerance to boron supply vary significantly between plants. Crops with high boron demand include corn, cotton, soybeans, alfalfa and cannula.

What About Deficiency in Soil and How Does that Affect Crop Yields and Nutrition?

A deficiency in boron has impacted the yield of 132 crops in at least 80 countries over the last few decades. According to the research, an adequate boron supply reduces the occurrence of empty grains and increases yields by up to five and a half percent in barley, multiplies spike length and plant pigment content, reduces the likelihood of sterility in wheat, and enhances tomato quality and shelf life.

Boron also improves yield in various crops and growing environments. A study in Brazil found that adding one kilogram of boron per hectare to seed cotton led to an increase in yield of 8%. Another study in Vietnam found that applying one and a half kilograms of boron per hectare increased the rice grain yields by 10%.

And in China, a study from 2011 showed that using water-soluble boron fertilizer, led to an increase in corn yields of 7.9%.

The University of Connecticut in 2020 investigated the effect of its boron-enriched SOP (sulfate of potash fertilizer) on the yield and growth of broccoli and tomato. These vegetables were chosen because they both need board and potassium. Broccoli has properties similar to other cruciferous crops, such as cauliflower and cabbage.

In the USA, 92% of broccoli and 90% of tomatoes are grown in California. An experiment with American Pacific Borates or 5E Advanced Materials as it’s now known provided four different SOP + B blends. When the boron-enriched SOP was used, broccoli yields more than doubled but the tomato results were less clear. Still, it suggests a linear relationship between the boron ratio and the yield effect.

It was also observed that there’s a narrow line between boron deficiency and toxicity, with one examination indicating that the optimal range for most species is 0.5 to five milligrams per kilogram of hot water extractable boron. Boron fertilization rates are typically 0.25 to three kilograms per hectare, as a range.

Boron is also a growing component of the fertilizer market. In 2019 the global fertilizer market was worth $156 billion, indicating that boron products account for a very small portion of the market. However, researchers believe that the market will grow at a compound annual growth rate of up to 12% by 2025 with a significant increase in borate consumption in the agricultural sector.

Boron is used as a fertilizer. Liquid fertilizers are a common type of agricultural fertilizer and are typically made up of about 10% boron with application rates, varying depending on soil conditions and other factors.

Some estimates suggest that boron demands in agriculture accounts for around 15% of total demand with annual growth rates ranging from 4 to 12%.

So it’s pretty clear that the role of boron in sustainable agriculture is to help improve soil health and fertility and increase crop yields. It’s clearly a valuable nutrient for sustainably increasing food production.

Boron and Food Security
PODCASTS, FOOD SECURITY

Podcast – Boron and Food Security

In today's podcast, we're going to look at boron and food security. Boron plays a considerable role in food utilization, principally by improving the nutritional value of fertilizers for plant growth development. It also increases crop yield through increased nitrogen fixation rates in soils deficient in micronutrients.
