Soil salinity can occur naturally or be caused by practices used on the farm – continuously irrigating with water that has a high salt concentration, for example. While some crops are tolerant to saline soils, high concentrations of some salts can be toxic to others. Salinity can also hinder a plant’s uptake of water and interfere with the absorption of nutrients. Read more for a closer look at the causes and consequences of salinity and sodicity, along with nutritional solutions to lower the impact on crops.
Although it may appear to be revolutionary, the concept of using plant growth-promoting rhizobacteria, or PGPR, has been with us for over 30 years. In the rhizosphere, the space immediately surrounding the roots of a plant, a complex series of interactions between the plant, microorganisms and the soil is in place. This unique environment supports a microflora that includes both beneficial and pathogenic microorganisms and exerts a significant influence on the growth and productivity of plants.
The Green Revolution of the 1960s sought to greatly increase agricultural production through the introduction of high-yield crops, chemical fertilizers, and synthetic herbicides and pesticides. With these new advancements, it was suddenly possible to grow more food on the same number of acres, to better meet the needs of a growing global population.
One thing that became somewhat overlooked during the Green Revolution (and the decades that followed) was soil organic matter. However, we are finally starting to recognize the value and impact that soil organic matter content has on crops, and actions are being taken to improve it.
As the world’s food demand grows, agricultural food production is also on the rise. This comes with the related challenges of poor yield, drought, pests and weeds that can negatively impact both productivity and the environment.
While fertilizers and pesticides play a significant role in attempting to overcome some of these obstacles, agricultural biologicals can make a crucial contribution toward the goal of making intensive agricultural production more successful and sustainable.
Safe for the environment, biologicals make crops healthier, with improved defenses against diseases and pests, and better able to withstand abiotic stress. The crop is well-prepared for early season growth and has a good vigor, with enriched root and shoot biomass and improved nutrient uptake and use.
Soil salinity can occur naturally or be caused by human activity – continuously irrigating with water that has a high salt concentration, for example. While some crops are tolerant to saline soils, high concentrations of some salts can be toxic to others. Salinity can also affect a plant’s uptake of water and absorption of nutrients.
In this blog post, we will take a closer look at the causes and consequences of salinity and sodicity, and how producers can take a nutritional approach to lower the impact on their crops.
