1、Effects of Boron and Lime on Productivity of Garden Pea under Acidic Soils in Northwestern Himalayas

An experiment comprising seven treatments was conducted to study the effect of boron and lime integrated with organic manures and nitrogen, phosphorus, and potassium (NPK) fertilizers on garden pea productivity.

2、Soil boron fertilization: The role of nutrient sources and rootstocks in citrus production

Boron availability in the soil and concentration in the leaves, as well as the fruit yield and quality of trees were evaluated. Soil B extracted with hot water and total leaf B positively correlated with doses of the nutrient applied to the trees.

3、Sulfur in organic farming

Sulfur (S) in organic farms can be supplied together with S containing approved fertilizers or raw S from natural sources. Even if S deficiencies in plant nutrition are reported in conventional agriculture, S fertilization in organic farms is not of practical importance up to now.

4、Reactions of boron with soils

Application of lime increases B fixation by soils because it raises the soil solution pH. In addition to its effect on soil pH, calcium carbonate also acts as an important B adsorbing surface in calcareous soils (Elseewi, 1974; Elseewi and Elmalky, 1979; Goldberg and Forster, 1991).

Short‐Term Integrated Application of Nitrogen, Phosphorus, Sulfur, and Boron Fertilizer and the Farmyard Manure Effect on the Yield and Yield Components of

The effort to identify and develop efficient strategies for using organic nutrient sources as fertilizer is urgently needed, given the current global shortage of chemical fertilizers and their expected negative impact on food supply.

Mixing Manure with Chemical Fertilizers, Why?and What is After?

Due to the benefits of integrated use of organic manure and chemical fertilizers to crops yield, it is therefore suggested that the combined use of organic manure with chemical fertilizers be applied continuously.

Effects of boron, potassium, sulfur, magnesium application on rapeseed and mulberry yield and quality

Field trials of boron (B), potassium (K), sulfur (S) and magnesium (Mg) application on rapeseed (Brassica napus) and mulberry (Morus nigra) in eastern Hubei province, PR China were used to study the effects of these nutrients on crop yield and quality.

Application of sulfur, boron and zinc recorded the higher uptake and was significantly superior to control and on par with treatments receiving sulfur, boron and zinc individually.

Soil solution from plots receiving lime and fertilizer had increased Ca/Al and base cation/ aluminum (BC/Al) ratios above critical levels. The addition of herbicide alone caused increased soil solution Al and H+ concentrations and reduced Ca/Al ratios to critically low levels.

Effect of potassium, sulfur, boron, and molybdenum fertilization on alfalfa production and herbage macronutrient contents

Potassium, S, B, or Mo fertilizer application also did not have a marked effect on alfalfa yield during this study. Combinations of K, S, B, and Mo fertilizer had variable effects and the effects were dependent on the combination of fertilizer, sources, and levels.

Lime sulfur solution is a commonly used pesticide primarily for preventing and controlling plant diseases. Boron fertilizer, on the other hand, is a nutrient-based fertilizer that provides boron, an essential element for plant growth. Below is a detailed analysis of whether lime sulfur solution can be mixed with boron fertilizer:

1. Mechanism of Lime Sulfur Solution

Lime sulfur solution consists of copper sulfate, quicklime, and sulfur. It functions as a fungicide, insecticide, and soil pH regulator. In plant disease management, it effectively inhibits the growth of pathogens, reducing the incidence of diseases.

2. Mechanism of Boron Fertilizer

Boron fertilizer contains boron, which enhances plant stress resistance, promotes growth, and improves crop yield and quality. Boron is critical for plant development, particularly during active growth stages.

3. Potential Issues of Mixing Lime Sulfur Solution with Boron Fertilizer

Although both substances aim to improve plant health and disease resistance, their distinct compositions and mechanisms may lead to adverse effects when combined:

(1) Reduced Efficacy

• Copper sulfate and quicklime in lime sulfur solution may decrease the availability of boron in boron fertilizer, compromising its effectiveness.
• Sulfur in lime sulfur solution could react with boron to form insoluble sulfates, further reducing boron’s bioavailability.

(2) Impaired Absorption by Plants

• Compounds in lime sulfur solution (e.g., copper sulfate, quicklime) might alter soil pH, reducing boron’s accessibility to plants.
• These compounds could also interfere with root absorption capacity, limiting boron uptake.

(3) Soil Environmental Risks

• Sulfur in lime sulfur solution may react with soil organic matter, producing toxic gases like hydrogen sulfide, harming soil health and plant growth.
• Copper sulfate in lime sulfur solution could increase soil heavy metal content, posing long-term environmental and plant health risks.

4. Recommendations

To avoid potential issues from mixing:

• Timing: Avoid applying boron fertilizer simultaneously with lime sulfur solution.
• Selection: Choose boron fertilizer varieties suited to local soil and crops, following recommended dosages.
• Monitoring: Track soil conditions and adjust fertilization strategies to ensure safe and healthy crop growth.

Mixing lime sulfur solution with boron fertilizer requires caution due to differences in their components and mechanisms. To ensure agricultural efficiency and safety, prioritize proper fertilizer selection, timing, and soil management practices.
