Description
The Root System of Fruit Plants provides the horticulturist with the information he needs to be able to choose an adequate method for discovering the causes of weak growth in fruit-bearing plants, for determining the correct depth of soil treatment in orchards and soft-fruit plantations, and for improving the system of agrotechnical measures that will ensure high yields of fruit.
Many of these techniques can be employed in studying the root systems of forest trees, decoratives, and grapevines, and some arc also applicable for the examination of vegetables and field crops.
The book is recommended for research workers, teachers, post-graduate students, and undergraduates of agricultural faculties and colleges, and for practising agronomists.
The book was translated from the Russian by Ludmila Aksenova, and was first published by Mir Publishers in 1971.
