1、Calcium and Boron Fertilization Improves Soybean Photosynthetic

Foliar fertilization with calcium (Ca) and boron (B) at flowering can promote flower retention and pod fixation, thereby increasing the number of pods per plant and, in turn, crop productivity.

2、Foliar fertilization of soybean: Is it useful to supplement primary

For suspected problem fields, a single application of N-P-K fluid fertilizers having a low proportion of N and a low-salt K source should be safe (to minimize leaf burning and yield decrease) and may produce economical yield responses when these problem fields are targeted for application.

3、Thinking about using foliar fertilizers in soybeans?

This article will focus on the question of whether using foliar-applied fertilizer products in soybeans can increase yield and profitability. Crops like soybeans obtain the bulk of their nutrients by extracting them from the soil as they take up water.

4、The Impact of Foliar Fertilization on the Physiological Parameters

The application of basic mineral fertilizers in combination with foliar fertilization had a significantly positive impact on the quality indicators of soybean seeds. The highest yields were achieved when the foliar treatment was applied in the early pod formation stage.

5、Results of Foliar Fertilizer Application in Soybean

The conclusion: foliar fertilizer products, similar to those tested, are not recommended for use by North Dakota soybean producers in the absence of symptoms of nutrient deficiency. This research was conducted a part of the “Science for Success” project funded by the soybean checkoff.

New study finds foliar fertilizers rarely increase soybean yield

A recent study conducted by agronomists from 16 U.S. states shows that the use of foliar-applied nutrient products on soybean crops does not consistently increase yield.

Foliar Fertilizers Rarely Increase Yield in US Soybean

At nutrient application rates currently recommended by foliar fertilizer manufacturers, there is no evidence that fields that receive foliar fertilizer should be expected to have different grain protein or oil content as compared to fields that do not receive foliar fertilizer.

Fertilizer Considerations for Soybeans

To maximize this yield potential, it is increasingly important to analyze and maintain soybean fertility. This is not only due to increased soybean yields but also increases in corn yields, environmental concerns, and financial considerations.

The Benefits of Soybean Foliar Fertilizer Application

Many AgroLiquid fertilizer products have been designed to be safe for foliar applications in soybeans, minimizing the risk of crop injury and improving the availability of those nutrients in the plant.

What Fertilizer Is Best for Soybeans? For Maximum Yield

Choosing the right fertilizer for soybeans can significantly impact their growth, nutrient uptake, and overall productivity. This comprehensive guide delves into the intricacies of soybean fertilization, exploring the best fertilizer options, application methods, and factors to consider for optimal results. Understanding Soybean Nutrient ...

Soybeans are a critical oilseed and protein crop, and their yield and quality directly impact the economic benefits of agricultural production. Foliar fertilization, as an efficient supplemental method, can rapidly provide essential nutrients to soybeans, promoting healthy growth and higher yields. Below, we detail the optimal foliar fertilizer choices, application methods, and precautions during the pod-forming stage to help farmers improve soybean productivity and quality.

Optimal Foliar Fertilizer Choices

1. Potassium Dihydrogen Phosphate (KH₂PO₄) This common foliar fertilizer is quickly absorbed by plants and promotes soybean growth. It contains phosphorus and potassium, both vital for photosynthesis and root development.

2. Borax (Boric Acid) Boron, an essential micronutrient, significantly impacts pod formation and seed maturation. It enhances cell division, strengthens disease resistance, and improves fruit quality.

3. Urea A nitrogen-based fertilizer, urea is crucial for protein synthesis in leguminous crops like soybeans. Foliar urea applications rapidly supplement nitrogen, boosting leaf growth and flower bud differentiation.

Application Methods

1. Dilution Ratio Follow instructions on the fertilizer package or local agricultural guidelines. For example, dissolve 0.1–0.2 grams of potassium dihydrogen phosphate per liter of water.

2. Timing Apply foliar sprays during the pod-forming stage in the early morning or late afternoon to reduce evaporation and ensure effective absorption.

3. Dosage Adjust based on plant size and soil fertility. A typical dose is 10–20 milliliters per plant per application to avoid leaf burn.

4. Uniform Coverage Spray evenly across all leaf surfaces, focusing on veins and edges to maximize nutrient uptake.

Precautions

1. Avoid High Temperatures Heat accelerates nutrient loss, so apply during cooler periods (morning/evening).

2. Safety Measures Wear gloves, masks, and protective clothing to prevent skin irritation or inhalation of chemicals.

3. Avoid Over-Fertilization Excessive use can lead to excessive vegetative growth, pest susceptibility, and reduced soybean quality.

4. Monitor Plant Response Discontinue use immediately if abnormalities (e.g., leaf spots, wilting) occur and seek expert advice.

Scientific selection and proper application of foliar fertilizers, combined with sound agricultural practices, can significantly enhance soybean yields and quality. Farmers are encouraged to continuously learn and adopt new techniques to elevate agricultural productivity.
