Hi reader of PlantVillage,

We are a public good that receives over 100,000 new visitors a month. We have had over 7 million people around the world come to our site and we are the largest source of free, open access science-based advice on crop health in the world. We want to help you, and the global community of people growing food (over 500 million people) access knowledge on growing crops. But we are really struggling right now for funds. We invested over $500,000 in making PlantVillage. You can donate to Penn State University’s PlantVillage fund and 100% of the funds will go to supporting PlantVillage. That is new knowledge, buying phones for African farmers and improving our AI extension system, Nuru.

We don’t want to have advertisements and we want to improve our content. Please help! Anything you can give would be great! The average donation to Wikipedia is $15. But, really, whatever you can give! If you have an Android phone to donate please email dhughes@psu.edu and we will re-package for farmers in Kenya. If you cannot give anything, that is OK. Enjoy PlantVillage and happy growing!

Thanks. David Hughes, PlantVillage co-founder
