The Effect of Organisms P and P From Several Sources on the Availability of Soil P, Absorption of Plants, and the Growth of Lamtoro (Leucaena Diversifolia) in the Soil of Typic Paleudult

Introduction

Soil Ultisol is the most extensive type of soil in Indonesia, but often has low fertility, especially related to the element of phosphorus (P). Efforts to increase the availability of P in the soil have become the focus of many research, which includes the use of organic fertilizer such as chicken manure and inorganic fertilizer such as rock phosphate (RP). What's more, in recent years, the use of biological fertilizer, especially P and mycorrhizal solvent organisms, is getting more attention, given the satisfactory results, especially in annual crops.

The Importance of Phosphorus in Soil

Phosphorus is an essential element for plant growth and development. It plays a crucial role in photosynthesis, root development, and flower and fruit formation. However, phosphorus is often the most limiting nutrient in Ultisol soils, which can lead to reduced crop yields and lower soil fertility. Therefore, it is essential to explore alternative methods to increase the availability of phosphorus in the soil.

The Role of P and P Organisms in Soil Fertility

P and P organisms, such as mycorrhizal fungi, play a vital role in improving soil fertility. These organisms can increase the availability of phosphorus in the soil by solubilizing insoluble phosphorus compounds and making them available to plants. Additionally, P and P organisms can also improve soil structure, increase soil water-holding capacity, and promote the growth of beneficial microorganisms.

The Effect of P and P Organisms on Soil P Availability

This study aims to explore the influence of various P organisms, both the P, Mycorrhizal Solvent Organism, and the combination of both, as well as various sources of P, namely rock phosphate and chicken manure, against the availability of soil P, absorption of P by plants, and the growth of lamtoro plants (Leucaena diversifolia). The study was conducted using a factorial random group design consisting of two factors: P. Organisms and P. Sources.

Research Methodology

The treatment of organism P consists of M0 (without), M1 (P), M2 (mycorrhiza), and M3 (combination of M1 + M2). The source of P used is P0 (without), P1 (Rock Phosphate), and P2 (chicken manure). Each treatment is repeated three times, producing a total of 12 treatments. Each treatment is mixed with 5 kg of dry soil, with the soil sample taken from Typic Paleudult in Simangambat Village, Barumun Tengah District, Central Tapanuli Regency. For each polybag, planted one lamtoro plant.

Measurements

Measurements carried out include P-Avors of Soil, N-Total Soil, Percentage of C, PH, Plant Height, Root Bintil Weight, Dry Weight of the Upper Plants, and N and P. Uptakes.

Results and Discussion

The results showed that the use of P organisms significantly increased N-total soil. However, there is no significant effect on the availability of soil P, plant height, root nodule weight, plant dry weight, as well as N and P. Absorption on the other hand, the source of P has been proven to have a significant effect in increasing the availability of soil P, although it does not significantly affect n n -Total soil, percentage C, pH, plant height, upper plant dry weight, as well as N and P. absorption of N and P.

The interaction between P and source P shows a significant effect on the availability of soil P, but does not have a significant effect on N-total soil, percentage C, pH, plant height, rooted nodule weight, dry weight of plants, as well as N and P. from the absorption of N and P. From All treatments carried out, the Solvent organism P (M1) shows the most positive influence on all measured variables. Meanwhile, the best source of P is obtained from chicken manure (P2). The combination of solvents P and chicken manure (M1P2) shows the most favorable results in all observed variables.

Conclusion

From the results of this study, it can be concluded that the use of P solvent organisms, especially in combination with chicken manure, has a high potential to increase the availability of soil P and support the growth of lamtoro plants. The use of this method can not only increase plant productivity but also contribute to more sustainable land management. Thus, the results of this study provide valuable insights for the development of agricultural techniques in ultisol soils that have low fertility, as well as to increase food security in Indonesia.

Recommendations

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

  1. The use of P solvent organisms, especially in combination with chicken manure, should be promoted as a sustainable method to increase soil P availability and support plant growth.
  2. Further research should be conducted to explore the potential of P solvent organisms in other types of soils and crops.
  3. The development of agricultural techniques that incorporate P solvent organisms and chicken manure should be encouraged to improve soil fertility and increase crop yields.

Limitations of the Study

This study has several limitations that should be acknowledged:

  1. The study was conducted in a controlled environment, and the results may not be applicable to other types of soils or crops.
  2. The study only explored the effect of P solvent organisms and chicken manure on soil P availability and plant growth, and did not investigate other potential benefits of these methods.
  3. The study did not explore the long-term effects of using P solvent organisms and chicken manure on soil fertility and plant growth.

Future Research Directions

Based on the results of this study, the following future research directions are suggested:

  1. Exploring the potential of P solvent organisms in other types of soils and crops.
  2. Investigating the long-term effects of using P solvent organisms and chicken manure on soil fertility and plant growth.
  3. Developing agricultural techniques that incorporate P solvent organisms and chicken manure to improve soil fertility and increase crop yields.

Conclusion

In conclusion, this study provides valuable insights into the effect of P solvent organisms and chicken manure on soil P availability and plant growth. The results suggest that the use of P solvent organisms, especially in combination with chicken manure, has a high potential to increase soil P availability and support plant growth. Therefore, the development of agricultural techniques that incorporate P solvent organisms and chicken manure should be encouraged to improve soil fertility and increase crop yields.
