1、Interaction among Fertilizers (Compatibility)

When preparing fertilizer solutions for nutrigation , each component solubility must be considered in order to avoid possible precipitate . The following mixtures reduce solubility and form the following sedimentations. • Calcium nitrate with sulfates = formation of CaSO4 precipitates ( gypsum).

2、Potassium Sulfate

Potassium is the only macronutrient that is not a structural component of cellular macromolecules.

3、The Effect of Potassium and Micronutrient Foliar Fertilisation on the

Both the two-fold foliar spray with micronutrients and the treatment combined with the application of potassium sulphate resulted in the enhanced content and accumulation of the elements examined.

4、EFFECT OF POTASSIUM AND MICRONUTRIENT FOLIAR

The aim was to evaluate the effect of foliar application of potassium sulphate (SOP) and micronutrients (Zn, Cu, Mn and B) on the content and accumulation of macroelements (N, K, Mg and S) in tubers at the stage of technological maturity.

GUIDANCE FOR COMPATIBILITY OF FERTILIZER BLENDING MATERIALS

Only solid blending components which are sources of primary (N, P and K) and/or secondary (e.g. Ca, Mg) nutrients are considered here. These blending components also include complex granular NPK/NP/NK fertilizers but fluid materials and micronutrients such as zinc and copper are not considered.

EFFECT OF POTASSIUM AND MICRONUTRIENT FOLIAR FERTILISATION ON THE

D et al. (2004), the evaluation of the potassium content in plants is a key element of effective potassium management and is comple-mentary to soil tests. Recent studies on the global scale demonstrate that potassium limits the production

Effects of Different Potassium Fertilizers on Growth and

The results showed that at 60 days after emergence，plant heights，stem diameters，the leaf SPAD values and biomasses of K 2 SO 4 treatment were significantly higher than those of KCl treatment，and those of K 2 SO 4 + KCl treatment were between the two treatments.

Knowledge of Fertilizer Mixing is Key for Improving Nutrient Use

Fertilizer blends or physical mixtures shall only be used if there is no risk of chemical or physical (e.g. moisture absorption) reaction between fertilizers in the blend or mixture that may...

Liquid Fertilizer Mixing Compatibility – What You Should Know

Blending liquid fertilizer materials can be an effective way to put multiple nutrients into a single fertilizer blend. The question is – what liquid materials are compatible? Additionally, can one test liquid blends to determine whether potential incompatibilities exist?

Potassium sources, microorganisms and plant nutrition: Challenges and

Potassium-solubilizing microorganisms (KSMs) can release K from soil/minerals into plant-available forms, which could be a sustainable option. The possibility of using KSMs as efficient biofertilizers to improve crop production has been increasingly highlighted by researchers.

Potassium sulfate is a commonly used chemical fertilizer, primarily providing plants with the potassium they need for growth. In agricultural production, proper use of potassium sulfate can effectively improve crop yields and quality. when applying fertilizers, it is essential to consider how potassium sulfate interacts with macroelements.

First, we must clarify the concepts of "macroelements" and "microelements". Macroelements, such as nitrogen (N), phosphorus (P), and potassium (K), are critical to plant growth and form the foundation of plant nutrition. Microelements, including iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), molybdenum (Mo), and others, are required in smaller amounts but play vital roles in plant development.

When fertilizing, it is necessary to select appropriate nutrients based on crop requirements and soil conditions. If only potassium sulfate is used without supplementing other macroelements, crops may suffer from nutrient deficiencies, disrupting their growth. combining potassium sulfate with other macroelement fertilizers ensures plants receive comprehensive nutrition.

Specifically, potassium sulfate can be paired with the following macroelement fertilizers:

1. Monoammonium Phosphate (MAP): This high-phosphorus fertilizer provides abundant phosphorus, promoting root development, nutrient absorption, disease resistance, and drought tolerance.

2. Calcium Nitrate (Ca(NO₃)₂): Rich in nitrogen, calcium nitrate supports leaf growth, photosynthesis, and yield improvement.

3. Urea (NH₄NO₃): A nitrogen-rich fertilizer, urea enhances root development, nutrient uptake, and stress adaptability.

4. Potassium Magnesium Sulfate (K₂MgSO₄): This fertilizer supplies both potassium and magnesium, improving root health, nutrient absorption, disease resistance, and stress tolerance.

5. Potassium Borosulfate (K₂B₄O₇·10H₂O): Combining potassium and boron, it promotes root growth, nutrient uptake, disease resistance, and stress resilience.

fertilization strategies should align with crop needs and soil conditions. By balancing potassium sulfate with other macroelement fertilizers, plants receive well-rounded nutrition, fostering growth and higher yields. Additionally, careful attention to dosage and application methods is crucial to avoid soil salinization and environmental pollution.
