Vegetable Farming in Zambia: How We Use A Venturi Injector To Fertigate Our Crops
Вставка
- Опубліковано 10 лис 2022
- Fertigation is the term used to describe the application of fertilizers or other nutrients to plants via the irrigation network. On our farm, we use a venturi injector, a device that allows the nutritious inputs (which have been dissolved into water) to mix into the irrigation supply and then be delivered to the plants. The mixture than be absorbed directly by plants when they uptake water.
This video summaries our journey from a time when all our liquid fertilizers were applied via foliar sprays to our introduction our first, simple fertigation system at Riverside 1, which is shown in action.
We also break down the advantages of using a venturi injector to take our fertiliser right where we want it to go.
Share Share Share! I believe that will make African agriculture stronger and help feed our people.
Indeed.
I love this channel. So factual. Platinum information sharing. So much needed in Africa. This brother was born for this
Thanks. Glad it is helpful.
Nice!...thanks for the video!...New subscriber from Zimbabwe 🇿🇼
Welcome
I have installed this venturi system on my farm, it really saves on time and also the cost of the labour to do so. Worth it.
It's definitely worth it.
Our biggest challenge in getting started with fertigation was the learning curve, especially figuring out how much fertiliser to apply per particular area.
We also struggled at first to have the system and its benefits accepted by the team.
But now they are on board with it and using the venturi setups extensively across both farms.
All the best.
@@mondofarms4343 So what helped you figure out how much fertilizer to use for how many drips?
Always refreshing watching your videos. Practical and very informative. Keep it up
Thanks, will do!
Thank you for sharing. Your video is very informative. Wishing you all the success and stay blessed.
Thank you! You too!
Hi Mondofarms we came across your channel recently and we are loving it. You speak and explain very clearly and we are enjoying you’re story-like narrations. The only downside is that we don’t understand Zambian and would love to have subtitles when you do speak in your local language. Well done on a well thought out channel and good luck in your farm.
Thanks. Being able to include our local languages was a major inspiration for me to set up this channel.
Our tongues are so rarely heard, and the channel has been well appreciated by people across Zambia and in neighboring countries that understand. They have always been my primary target audience.
Tell the truth, I never expected to reach many audiences further afield, which had been a wonderful surprise.
But, yes, I will try to be more inclusive with subtitles summarizing what is said in future videos.
Wonderful video!
Glad you liked it!
Very informative thank you Sir
Glad it was helpful!
Hope one day you’ll do an in person course. Would love to come spend a week and even learn 1% of what you know. Amazing video and that last meal looked mint.
Thanks. We are working towards having facilities for such in the future.
Kimberley will be able to host and accommodate training participants.
But we're still a couple of years away from that. Meanwhile, we had our first Farmers Field day last November, which was well publicized. There should be one or two more later this year.
I have almost watched most of ur video just tonight, and they are so addictive 😍. Well done, and keep up the good work. I think you need a drone 🤔 for video and for security purposes 😉 too. Thanks for educating us in farming.
Awesome! Thank you!
Hello mondo farms. I like your explanations especially the clarity. Keep it up with the good works. My only advise is that install the Venturi before the filter so that in the event that your fertilizer has some solid particles they will be trapped by the filter and you will save your drip lines. Great work👍
Great idea and much appreciated.
Gold!
Thanks 😊
Very inspiring. Keep up the good work. Are you able to explain how you determine the fertilizer mixing ratios?
Sure, we will feature it in a follow-up video.
But in the meantime, we advise you to get guidance from agronomists at your fertilizer companies.
Thanks so much for this video , Watching and following you from ghana. can the venturi be integrated with down gravity tank?
Hi there. Yes, for the venturi syphin to work, all that's necessary is for the pipe to have enough water pressure to enable the bernoulli effect.
In our case, the water was flowing via gravity from a water reservoir.
Your supplier of the venturi will help you with such details when you're ready.
@@mondofarms4343 thanks so much mentor....God willing in the near future, i'll be coming for execution .
Hello Mondofarms, good piece as usual. The system really helps with avoiding the mannual application of ganular ferts. How do you ensure that you apply the correct amounts of ferts using a venturi as you irrigate? i note you are using a 20litre bucket to fertigate, how long do you irrigate as you fertigate with a 20l mixture of fertilizer? Appreciate your response.
Those are questions we used to ask ourselves before we adopted the venturi system. We were really stuck with doubts and hesitation.
But in the end, we just got started with it and figured out the quantities. The fertiliser companies have agronomists who can be really helpful in such things.
@@mondofarms4343 Thank you.
How do you measure the quantity of the fertilizer each plant has got when using venturi, how sure au that each of yo blocks need 20 litres,
But thanks for the best work yo doing.
There's some calculations we do in terms of fertiliser load per area.
You remind of how we also had a lot of doubts before we just decided to just get on with it. We sat on the venturi syohins we had bought for over a year!! We were guilty of over-thinking things and suffered from what is often called paralysis by analysis.
Just do it. The suppliers you buy the fertigations systems from, and the fertiliser companies will guide you accordingly.
Can this be moved to other field or you just have to wait until the field you have site to come the end
Im sure one could design mobile units, but we didn't go that route.we fertigate and chemigate quite regularly, so moving them would become another issue.
I hope you saw the part in the video where I mentioned that we would be putting fertigation stations in strategic areas around the farm to cover different crops there.
What size is the venturi and the main pipe? What was the consideration, i notice the venturi pipes are smaller than your main line. How to measure foliar and grannular fertilizer
Great questions. You can get better guidance from the companies that sell venturi syphons and from the agronomists at the fertiliser suppliers.
All the best.
Okay I have alot to learn
Muliba pondo
Ba Tembo, we are all constantly learning.
One of the best things about farming is that the learning never ends. At some point, it will humble you and make you shed tears of frustration and despair. But when the rewards finally come, there are few other feelings like it.
I'm just glad to be able to help so many people with our channel.
All the best.
That means the ratio of water : fertilizer is mixed automatically with efficiency
😊
Are you vegitates inorganic or organic food. Great job.
Sorry, we try to run our farm as a business. That means being quite realistic about when and how we have to use chemical fertilisers and pesticides in order to optimize yields and returns. From time to time and wherever possible, we use biological agrochems if appropriate and worthwhile.
We don't yet have the luxury of trying full-on organic farming.
The agricultural world learned a lot of lessons about the risks of organic from what happened in Sri Lanka a few years ago.
Thanks.
I am really wondering if I can use this with rain pipes. What would you advise?
Yes, some people use venturi syphons with sprinklers as well.
But it is not as effective because of all the water that goes to waste by being sprayed around the leaves and the ground.
Drip is best for fertigation because the concentrated mixture is delivered right to the plant roots.
@@mondofarms4343 aah yes true. The efficacy is compromised. Here in Zimbabwe we use center pivots a lot for filed crops. I noticed recently that they use venturi for fertigation and the results are good so maybe the efficacy is not as good as in drip systems but it still works good.
What’s the name of that system so that I can order it online please, thanks so much the information.
Hi Herbert. It's just one of those generic items from China sold everywhere these days. The brand names are not that key at the price they cost.
Best of luck.
I feel as i have read flow of water in main line has to be from down to up
Sorry Mahesh, Im not sure I understand what you are saying or asking.
Could you rephrase?
Appreciate the information over these Venturi syphons...
Btw, can they pay already so you let us know 😂
Still waiting, but slowly getting somewhere with sponsorship and advertising engagement. Especially as the Channel grows and has more engaged subscribers like you.
Do you prune your cucumbers?
Please have a look at our videos that share how we grow cucumbers. We have several of them on our channel that give more details.
It would be nice for those people to contact you so you can advertise for them
Through advertising for them And
In helping them You are helping other African farmers.
You know if these sellers are Africans that sell those venturis I won’t count on them watching your videos
They probably don’t have any inclination and in a million years will never ever have any desire to follow social media , let alone follow you on UA-cam
Still waiting patiently 😪
How is this going?
It's going very well and the Team is now very used to them and their many advantages. Quite gratifying, considering the learning curve we had at first.
We actually bought another two units this month for other fields in the farm.
@@mondofarms4343 Thank you for taking the time to reply and letting us know that that is a sustainable system.
You should not be using a venturi injector in a vertical configuration
Thank you for your valued contribution to our channel.
😂😂 non-apologetic... But good information, thanks!
No worries!
