1、Lime and Phosphate Could Reduce Cadmium Uptake by Five Vegetables Commonly Grown in South China

To reduce heavy metal accumulation in vegetables, soil amendments (lime, phosphate compounds, silicate, bio-mixed organic fertilizer, etc.) were suggested to be effective. This technique of metal stabilization is of particular interest because of its cost-effectiveness and less disruptive nature.

2、Influence of Lime and Phosphorus Fertilizer on the Acid Properties of Soils and Soybean

However, application of P sourced fertilizers and lime rate is does not optimized for Assosa area (Figure 1). Therefore, this activity was designed to evaluate the Influence of lime rate and P fertilizer on the change of acid properties of the soil and soybean growth at Assosa soils.

Where available, application of inorganic fertilizer without soil test, on the long run, can increase soil acidity. It is also due to side effects of inorganic fertilizer on intensely cultivated soils [20].

4、Immobilization of cadmium and improvement of bacterial community in contaminated soil following a continuous amendment with lime mixed with fertilizers: A

The results indicate that the continuous application of lime mixed with organic manure or phosphate fertilizer is a very important measure to ensure the quality safety of rice and improve soil quality in a Cd-contaminated paddy.

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

Using chemical fertilizers or organic manure alone as amendments may bring negative effects to the quality of crops. Neither of these alone can sustain productivity. Hence, judicious uses of organic manure with chemical fertilizers are essential to augment productivity of crops.

Composition of Mobile Phosphate Fractions in Soils of the Pre

The introduction of lime and ground phosphate, together, provided much the same content of weakly bound phosphorus as application of phosphate alone after 1 year’s incubation; after 2 years of its content was lower than values obtained after application of phosphate alone.

Effect of Heavy Metals on Plant Growth and Ability to Use Fertilizing Substances to Reduce Heavy Metal Accumulation by Brassica Juncea L

When the amount of phosphate fertilizer increase the contents of heavy metals in plants decrease, in which the affects of phosphate fertilizer on Pb uptake by plants is the most evident.

Ameliorating acid soils by application of lime and/or P mineral fertilizer is among the leading option to restore the productivity of such chemically degraded soils (Somani, 1996; Mesfin, 2007; Brady and Weil, 2008; Fageria et al., 2011).

There is, therefore, a need to carry out determination of the nutrient use efficiency and residual value of phosphorus (P) upon application of different phosphate fertilizers and manure and their effects on acidic soils of smallholder mixed farms.

Mixing lime with phosphate fertilizer is a common practice in agriculture, but it is not without risks. Below is a detailed analysis:

I. Reasons for Mixing Lime with Phosphate Fertilizer

1. Soil Improvement

• Raising Soil pH: Lime is an alkaline substance that can significantly increase soil pH. This is particularly effective for improving acidic soils, as many crops (e.g., legumes, vegetables) thrive in neutral or slightly alkaline environments.
• Enhancing Soil Structure: Lime improves soil compaction and physical properties, making the soil looser and more conducive to root growth and nutrient absorption.

2. Enhancing Phosphorus Availability

• Increasing Phosphorus Solubility: When lime reacts with acidic components in the soil, it forms calcium phosphate precipitates, reducing phosphorus fixation by the soil and improving its availability.
• Boosting Phosphorus Uptake: Higher soil pH enhances plants’ ability to absorb phosphorus, which is critical for phosphorus-deficient soils.

3. Economic Benefits

• Cost Reduction: Using lime can reduce the amount of chemical fertilizers (especially phosphate fertilizers) needed, as it lowers soil phosphorus fixation.
• Yield Increase: Improved soil conditions enhance crop quality and yield.

II. Precautions for Mixing Lime with Phosphate Fertilizer

1. Risks of Overuse

• Soil Salinization: Excessive lime application over time can lead to salt accumulation, compromising soil aeration and water retention, which hinders crop growth.
• Soil Acidification: While lime raises soil pH, overapplication may paradoxically induce acidification, disrupting microbial activity and plant growth.

2. Environmental Impact

• Groundwater Contamination: Excess lime may leach into groundwater, polluting this vital resource.
• Pollution from Production: Lime production generates waste, and improper disposal can harm the environment.

3. Crop Adaptability Issues

• Crop-Specific Sensitivity: Different crops tolerate soil pH levels differently, and excessive pH adjustment may harm certain crops.
• Disease Risks: Some pathogens thrive in acidic conditions, so altering soil pH could inadvertently promote disease outbreaks.

Mixing lime with phosphate fertilizer has clear benefits in agriculture, particularly for improving acidic soils, enhancing soil fertility, and boosting crop growth. this practice carries risks, such as environmental harm and crop damage, if misused. Careful management, dosage control, and regulatory oversight are essential to ensure safety and effectiveness in agricultural applications.
