Optimizing Phosphorus Availability and Corn Growth in Inceptisol Soil: The Impact of SP-36 Fertilizer and Cow Manure

Introduction

Phosphorus is a crucial nutrient for plant growth, playing a vital role in photosynthesis, energy transfer, and nucleic acid synthesis. However, phosphorus availability in the soil is often a problem, particularly in certain soils like inceptisol, which can have low levels of phosphorus availability. This study aims to explore the effects of SP-36 fertilizer and cow manure on phosphorus availability and corn growth in inceptisol soil.

Background

Inceptisol soil is a type of soil that is characterized by its low levels of phosphorus availability. Phosphorus is essential for plant growth, and its availability in the soil is often a limiting factor. SP-36 fertilizer is a type of fertilizer that contains high levels of phosphorus, making it an effective tool for increasing phosphorus availability in the soil. Cow manure, on the other hand, is a natural source of organic matter that can increase soil pH and provide a medium for microorganisms to grow, which can help to decompose and release nutrients in the soil.

Methodology

This study was conducted in a glasshouse at the Laboratory of Soil Fertility Chemistry, Faculty of Agriculture, University of North Sumatra, and PT. Nusa Pusaka Kencana & Laboratory Analysis of QC (Asian Agri Group). The study used a factorial random block experimental design consisting of two factors with three replications. The first factor was the SP-36 fertilizer dose, which consisted of four levels (ppm/10 kg BTKO): P0 (0), P1 (100), P2 (200), and P3 (300). The second factor was the dose of cow manure, which consisted of four levels (g/10 kg BTKO): S0 (0), S1 (50), S2 (100), and S3 (150).

Results

The results of this study showed that the application of SP-36 fertilizer significantly increased the availability of phosphorus, absorption of phosphorus by plants, and the growth of corn plants. Cow manure also had a significant effect in increasing soil pH, organic carbon content, absorption of phosphorus by plants, and the growth of corn plants. In addition, the interaction between the application of SP-36 fertilizer and cow manure was proven to increase the absorption of phosphorus by corn and its growth significantly.

Discussion

Phosphorus is an essential nutrient for plant growth, and its availability in the soil is often a limiting factor. SP-36 fertilizer is a type of fertilizer that contains high levels of phosphorus, making it an effective tool for increasing phosphorus availability in the soil. The results of this study indicate that a higher dose of SP-36 fertilizer has a positive impact on the absorption of phosphorus by corn plants, which contributes to better growth.

Cow manure provides additional benefits in the form of increased soil pH and increased organic matter. An increase in soil pH can increase the availability of phosphorus, because at a higher pH, phosphorus in inorganic form is more available for plants. In addition, organic material derived from cow manure also functions as a good medium for the growth of microorganisms that help the process of decomposition and decomposition of nutrients in the soil.

The interaction between SP-36 fertilizer and cow manure has a more significant impact than the use of just one fertilizer. This shows the importance of a combination of fertilizer application in supporting plant growth, which can increase the overall harvest yield.

Conclusion

The application of SP-36 fertilizer and cow manure is an effective strategy for increasing the availability and absorption of phosphorus, as well as supporting the growth of corn plants in soil inceptisol. The results of this study can be a reference for farmers in choosing and managing fertilizer optimally, as well as providing deeper insights regarding the management of soil fertility to increase agricultural productivity. With proper management, it is expected that plant productivity can increase, which in turn can contribute to food security.

Recommendations

Based on the results of this study, the following recommendations can be made:

  1. Use of SP-36 fertilizer: The use of SP-36 fertilizer can be an effective tool for increasing phosphorus availability in the soil. A higher dose of SP-36 fertilizer can have a positive impact on the absorption of phosphorus by corn plants, which contributes to better growth.
  2. Use of cow manure: Cow manure can provide additional benefits in the form of increased soil pH and increased organic matter. An increase in soil pH can increase the availability of phosphorus, because at a higher pH, phosphorus in inorganic form is more available for plants.
  3. Combination of SP-36 fertilizer and cow manure: The interaction between SP-36 fertilizer and cow manure has a more significant impact than the use of just one fertilizer. This shows the importance of a combination of fertilizer application in supporting plant growth, which can increase the overall harvest yield.

Future Research Directions

This study provides a foundation for further research on the effects of SP-36 fertilizer and cow manure on phosphorus availability and corn growth in inceptisol soil. Future research can focus on the following areas:

  1. Long-term effects: The long-term effects of SP-36 fertilizer and cow manure on phosphorus availability and corn growth in inceptisol soil can be investigated.
  2. Different types of fertilizers: The effects of different types of fertilizers on phosphorus availability and corn growth in inceptisol soil can be investigated.
  3. Different types of organic matter: The effects of different types of organic matter on phosphorus availability and corn growth in inceptisol soil can be investigated.

Limitations of the Study

This study has several limitations, including:

  1. Small sample size: The sample size of this study was relatively small, which may limit the generalizability of the results.
  2. Limited experimental design: The experimental design of this study was limited to a factorial random block design, which may not capture the full range of interactions between SP-36 fertilizer and cow manure.
  3. Limited scope: The scope of this study was limited to the effects of SP-36 fertilizer and cow manure on phosphorus availability and corn growth in inceptisol soil, and did not investigate other potential effects of these fertilizers and organic matter on plant growth and soil fertility.
