Is it permissible to import plant nutrients that contain pig's blood in their composition, knowing that they are sprayed on crops that are eaten, such as vegetables and fruits?

Shaykh al-Islam, concerning the ruling on meeting impurities with pure substances, transmits from Imam Ahmad that Allah has forbidden carrion, blood, and the-flesh-of-swine. Thus, if the taste of any of these vile substances appears in what is used, then one is using these vile substances. Then he clarifies that the correct view is that if these vile substances (blood, carrion, and the-flesh-of-swine) fall into water or other substances and are consumed (dissolved), they cease to exist. Therefore, it appears that the use of compounds in which no trace of blood is visible is permissible, because in such a case, it is as if it does not exist.
