1、Lime and Phosphate in the Soil

In the long term, the result of liming seems to be to increase the negative charge on soil colloids and therefore to decrease adsorption and increase desorption of phosphate. The application of lime and phosphate to soils can have indirect (and often overlooked) effects on soil fertility.

2、Influence of Lime and Phosphate Fertilizer on Phosphorus Sorption and

Soil acidity can be ameliorated with application of lime while phosphate fertilizer often applied to raise concentrations of available soil P to an adequate level.

3、Effects of lime application on nitrogen and phosphorus availability in

Liming is commonly used to improve the productivity of acidic soils in agricultural systems. The addition of lime increases the availability of nutrients, which would otherwise be strongly...

Phosphate Fertilizer Type and Liming Affect the Growth and

In the context of phosphorus (P) exhaustion and low P use efficiency (PUE) in crop production, a field trial was designed on a low-P soil in southwestern Germany in 2020 and 2021 to investigate the effects of P fertilizer type and liming on maize growth and P uptake and PUE.

Effects of liming on phosphate availability in acid soils

When making lime recommendations or interpreting the data collected from lime-phosphate experiments, it is important to consider all the complex interacting soil and plant factors involved.

Long

Liming is a common management strategy for ameliorating soil acidity but that also causes many long-term effects on soils, crops and biodiversity (Holland et al., 2018).

Interaction of soil pH and phosphorus efficacy: Long

We analyzed a 36-year long-term field experiment regarding the effects of different P application and liming rates on plant growth and soil P concentrations with a crop rotation of sugar beet, wheat, and barley.

Interaction of liming and long

Therefore, in the present study, we investigated the response of crop yield and PUE to the long-term application of fertilizers and quicklime (CaO) in the acidic soil under wheat–maize rotation...

Soil phosphorus forms and fertilizer use efficiency are affected by

Liming combined with no-tillage (NT) can increase the efficiency of P use by accumulating soil P in more available forms and improving root exploration due to the absence of toxic Al 3+.

Influence of Lime and Phosphorus Application Rates on Growth of Maize

There was a significant effect of lime, P, and P by lime interactions on plant heights and dry matter. Without lime application, dry matter increased with increasing P rates but, with lime, dry mattes increased from 0 to 30 kg P ha −1 but declined from 30 to 100 kg P ha −1.

Lime and phosphate fertilizer are two commonly used agricultural inputs that play critical roles in soil amendment and crop growth. they exhibit certain antagonistic effects, primarily manifested in the following aspects:

1. pH Value Antagonism: Lime is an alkaline substance that neutralizes acidic components in the soil, raising its pH. In contrast, phosphate fertilizers are typically acidic, and excessive use can lead to soil acidification, lowering the pH. when applying lime, the dosage of phosphate fertilizer should be reduced to maintain soil pH balance.

2. Nutrient Content Antagonism: Lime contains high levels of calcium, enriching the soil’s calcium content, while phosphate fertilizer provides phosphorus. When lime is applied, phosphate fertilizer usage can be increased to meet crops’ phosphorus needs. overapplication of phosphate fertilizer may cause phosphorus excess, which could inhibit crop growth.

3. Soil Structure Antagonism: Lime improves soil structure, enhancing aeration and water retention. Phosphate fertilizers, meanwhile, boost soil organic matter, improving water-holding capacity and buffering ability. When using lime, practices like deep tillage and organic fertilizer supplementation can offset potential negative impacts of phosphate fertilizers on soil structure.

4. Crop Demand Antagonism: Different crops have varying nutrient requirements. For example, maize and wheat demand higher phosphorus, whereas soybeans and cotton require more nitrogen. When applying lime, phosphate or nitrogen fertilizers can be selected strategically based on crop-specific needs.

5. Environmental Factor Antagonism: Soil microorganisms influence fertilizer absorption. Calcium ions in lime may bind with iron and aluminum in the soil, affecting microbial activity, while phosphate fertilizers enhance microbial populations and activity. When using lime, measures like crop rotation and deep tillage can promote microbial recovery, maximizing fertilization efficiency.

lime and phosphate fertilizer both complement and antagonize each other in agriculture. Their application should consider soil conditions, crop requirements, and environmental factors to optimize results. Avoiding overuse of either prevents resource waste and environmental pollution.
