Improving the Effect of Phosphorus Application on Newly Reclaimed Red Soil Fields and the Feasibility of High-Rate Phosphorus Application on Phosphorus-Deficient Soils
Newly reclaimed red soil fields have a low total phosphorus content (generally below 0.4 g/kg) and high iron and aluminum contents. The phosphorus in the soil exists mainly as iron and aluminum phosphate compounds, which are not easily absorbed and utilized by crops. Therefore, when planting crops and economic forest trees in newly reclaimed red soil fields, emphasis should be placed on increasing phosphorus application.

In 2017, the price of sesame rose by 30% in half a year. How should farmers grow it to achieve high yields?
According to market data, in recent years, the price of sesame has risen from 6 or 7 yuan per jin to 8 yuan 90, but now the sesame market is in short supply, so sesame dealers have no choice but to use imported sesame, as much as 70%. In 2017, not only did domestic output decline, but abroad, countries like India also had insufficient output because of natural disasters last year, thus causing a large increase in sesame prices!

Fertilizer Requirements and High-Yield Fertilization Techniques and Timing for Sugar Beet in China
Fertilizer requirements and high-yield fertilization techniques and timing for sugar beet in China: Sugar beet is an important sugar crop. From spring sowing to autumn root harvest is the vegetative growth stage. During this period, the root system is well developed, the leaf canopy is lush, the yield per unit area is high, and nutrient requirements are large. In the second year, from spring planting of the mother plant to seed harvest is the reproductive growth stage, and nutrient uptake is relatively reduced.

Fertilisation Techniques and Timing for Persimmon Trees: Master the Nutrient Requirements for High Yields
The persimmon tree originated in the Yangtze River basin of China, extending east to Taiwan Province, and is widely cultivated in many provinces and regions. The fruit is often de-astringed before being eaten as a fruit; after proper treatment it can be stored for several months and can be eaten at any time of the year. Persimmons can also be processed into dried persimmons. So what are the nutrient requirements of
