Let's assume in your analogy God is the farmer. If God prepares His fields, tills the soil, break the ground and plants the seed, do you think that it won't grow? Doesn't God give the growth?

It won't grow until or unless the seed takes root and it is watered.

God prepared first century Israel for the visitation of the seed of the Word of God --- and yet the seed took root in only a small part of the ground that He had prepared.

Here is Charles Spurgeon on the matter:

"If I am to preach faith in Christ to a man who is regenerated, then the man, being regenerated, is saved already, and it is an unnecessary and ridiculous thing for me to preach Christ to him, and bid him to believe in order to be saved when he is saved already, being regenerate. Am I only to preach faith to those who have it? Absurd, indeed! Is not this waiting till the man is cured and then bringing him the medicine? This is preaching Christ to the righteous and not to sinners".[C. H. Spurgeon: The Warrant of Faith]

Using the farmer's analogy, it would be like waiting for the crops to grow before casting the seed into the field.

You're wrestling with a great truth of the gospel; not unlike Augustine or Spurgeon or any one of us true Reformer; doesn't God open our ears, unblind our eyes, and blesses our hearts to receive His word? It goes to the heart of the blessed Cyprian's question to Augustine, "What do you have that you have not received?" Spurgeon also grapped with this question:

One week-night, when I was sitting in the house of God, I was not thinking much about the preacher's sermon, for I did not believe it. The thought struck me, How did you come to be a Christian? I sought the Lord. But how did you come to seek the Lord? The truth flashed across my mind in a moment—I should not have sought Him unless there had been some previous influence in my mind to make me seek Him. I prayed, thought I, but then I asked myself, How came I to pray? I was induced to pray by reading the Scriptures. How came I to read the Scriptures? I did read them, but what led me to do so? Then, in a moment, I saw that God was at the bottom of it all, and that He was the Author of my faith, and so the whole doctrine of grace opened up to me, and from that doctrine I have not departed to this day, and I desire to make this my constant confession, "I ascribe my change wholly to God." - A Defense of Calvinism

Spurgeon is right. We are the deliverers of the message. We don't know who's heart God has cultivated. We are asked of God to be faithful in throwing the seed out so that He will use it in the proper place.
