Crop nutrient requirements and management in protected cultivation. Protected cultivation systems are used throughout the world as a powerful instrument to produce crops. Pieter H B de. Agricultural land accounts for only 3.5 percent of the land area of Egypt. Two thirds of the agricultural land is alluvial soil, fertilized for thousands of years by the Nile floods, and one third is land recovered since the 1950s. Rainfall is minimal and almost all the agricultural land is irrigated. Soil salinity and water logging are important problems in the reclaimed areas.

Nutrient management is critical in order to increase or maintain crop yields on a single parcel of agricultural land. To meet crop needs throughout a growing season soil fertility must be consistently high. There are fourteen nutrients that are supplied to crops from soil and fertilizer sources. Of these, 6.

Fertilizers are plant nutrients, required for crops to grow • Crops need energy light CO 2, water and minerals to grow • The carbon in crops originates from CO 2 absorbed through the leaves • Crops absorb water and plant nutrients from the soil • Plant nutrients are building blocks of crop material. Without nutrients the crops can not grow. The book covers the essentials of plant nutrition and irrigation management. Throughout the 232 pages of the book, the author shares his knowledge on the most important aspects of crop nutrition and irrigation, including: Plant nutrients, their roles in plants and behavior in soil and water; Fertilizer management practices. Crop nutrition is important for the production of high-yielding, top quality fruit crops. Good soil and water management practices are important for a crop's efficient use of nutrients from organic and inorganic fertilizer. Nutrients must be dissolved in the soil water for root uptake. There is a need of integrated, balanced and effective fertiliser management to take care of proper replenishment and compensation of nutrient losses from soil and locked-up nutrients in the growth of horticultural crops.
