2、A macro‐element model for non‐linear soil–shallow foundation–structure interaction under seismic loads: theoretical development and experimental validation

Based on this comprehensive validation process against a set of independent experimental results, a unique set of macro-element parameters for shallow foundations on dense sand is proposed, which can be used to perform predictive analyses by means of the present model.

In its present state of development the model can be used for strip and circular footings in purely cohesive or purely frictional soils. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

4、Micro/Nanofertilizers for Sustainable Agriculture: A Review

Poorly effective traditional fertilizers and resulting environmental pressure have led to the development of micro/nanosized nutrients. Although a growing number of laboratory studies confirm that micro/nanofertilizers (MNFs) can promote plant growth and improve nutrition, they are not yet commercially produced in force. One major barrier is the higher raw material and processing costs ...

5、Effect of The Combination of Organic and Inorganic Fertilizers on The Growth and Production of Melons (Cucumis Melo L)

The use of organic fertilizer can increase productivity in a relatively long time. Therefore, research needs to be done by combining the use of organic and inorganic fertilizers to increase melon productivity.

One way to accomplish this is to utilize elements of maximum size possible in the model without losing the accuracy. These elements are referred to herein as macro-elements. These elements should satisfy as many boundary conditions as possi- ble, if not all four conditions.

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.

In structural engineering, soil–structure interaction (SSI) is an important phenomenon that has to be taken into account. This paper presents a 3D non-linear interface element able to compute SSI based on the “macro-element” concept.

Manure and Mineral Fertilizer Effects on Crop Yield and Soil Carbon Sequestration: A Meta

Manure application to soil has declined globally due to increased availability of mineral fertilizers. However, mineral fertilizer overuse has caused serious consequences for soil quality and the environment.

Nitrogen Dynamics in Soil Fertilized with Slow Release Brown Coal

The results support the notion that BCU granules can be used as a slow release and enhanced efficiency fertilizer for increasing availability and use efficiency of N by crops.

Muskmelons (Cucumis melo) are a popular summer fruit cherished for their sweet flavor and nutritional richness. In agricultural production, the rational use of fertilizers is critical to enhancing both the quality and yield of muskmelons. Macro-element fertilizers, which contain essential nutrients like nitrogen (N), phosphorus (P), and potassium (K), play a vital role in plant growth and development. This article explores whether macro-element fertilizers are suitable for muskmelons and why they should be used.

I. Analysis of Muskmelon Growth Requirements

1. Nutritional Needs: As a light- and temperature-loving crop, muskmelons require significant amounts of N, P, and K during development. Nitrogen promotes leaf growth and fruit formation, phosphorus supports root development, fruit ripening, and stress resistance, while potassium enhances disease resistance and drought tolerance.
2. Growth Cycle: From planting to harvest, muskmelons undergo multiple growth and fruiting cycles over several months, leading to varying nutrient demands at different stages.
3. Environmental Conditions: Factors such as temperature, humidity, and light influence nutrient absorption and utilization efficiency, requiring adaptive fertilization strategies.

II. Roles of Macro-Element Fertilizers

1. Rapid Nutrient Replenishment: These fertilizers provide immediate access to essential N, P, and K, accelerating recovery and growth—critical for boosting yield or improving quality in short growing seasons.
2. Balanced Nutrient Supply: Formulated with optimized N-P-K ratios, they address nutritional needs at various growth stages, preventing imbalances caused by over- or under-application of single elements.
3. Improved Fertilizer Efficiency: Compared to single-nutrient fertilizers, macro-element blends enhance absorption, reduce nutrient loss, and improve cost-effectiveness.

III. Feasibility of Using Macro-Element Fertilizers for Muskmelons

1. Economic Considerations: While macro-element fertilizers are pricier than single-nutrient options, their higher efficacy and lower application rates make them economically viable.
2. Technical Feasibility: Modern agricultural practices enable precise application, ensuring efficient use and minimizing negative impacts from over-fertilization.
3. Ecological Impact: Appropriate use maintains soil health and ecological balance. Excessive application may lead to soil salinization or nutrient imbalances, but moderate use supports sustainable growth.

IV. Recommendations and Precautions

1. Scientific Nutrient Ratios: Adjust N-P-K proportions based on growth stages and soil conditions to avoid deficiencies or excesses.
2. Combine with Organic Fertilizers: Integrate organic matter (e.g., animal manure, green manure) to improve soil structure and fertility, fostering healthier plants.
3. Regular Soil and Plant Testing: Monitor nutrient levels periodically and refine fertilization plans to ensure optimal growth and high-quality yields.

Macro-element fertilizers are both feasible and beneficial for muskmelon cultivation. their use must align with scientific principles to ensure healthy growth, high yields, and superior quality. By balancing efficiency, economy, and ecology, farmers can maximize the advantages of these fertilizers.
