The photo gallery includes dozens of high quality original photos showing typical response of various crops to the application of potash fertilizer, and potassium deficiency symptoms in leaves.
Search function can be used to find crops and locations where pictures were taken by IPI and others in China, India, Brazil, Egypt, Argentina, Bangladesh, Israel and more.
There is a description on each slide and tools to mark favorites, and share pictures via e-mail, Twitter and Facebook are provided.
